TMC2084-HT-E2 CircLink Controller | Microchip | Remote I/O
The Microchip TMC2084-HT-E2 is a standalone-mode CircLink controller functioning as an intelligent remote I/O controller in a 48-pin LQFP package. The verified source identifies a 40 MHz device with CMOS interfaces, operation from 3 V to 3.6 V, and compatibility with an enhanced token-passing network controlled by a TMC2074 or TMC2072 host node. Its primary role is distributed I/O expansion rather than general-purpose computation or standalone sensor conditioning. A CircLink controller is a dedicated network interface and remote I/O control device. In this architecture, the TMC2084 attaches external I/O nodes to a token-passing serial network, allowing a host controller to supervise distributed digital inputs and outputs. This hierarchy places the device among interface controllers, serial I/O controllers, semiconductors, and CircLink network components. The verified comparison data identifies the TMC2084-HT as an active Microchip device in a 48-pin rectangular low-profile QFP package. The listed electrical data includes a 40 MHz clock, 3 V minimum and 3.6 V maximum supply limits, CMOS technology, a 0.5 mm pitch, and 7 mm package width. These characteristics make it suitable for established CircLink equipment requiring the documented package and supply configuration. The controller uses enhanced token passing rather than a generic host peripheral protocol. In standalone mode, network nodes are controlled by a TMC2074 or TMC2072 host through the CircLink network. Because traffic depends on network behavior, firmware, timing, and system topology, designers should follow the manufacturer datasheet for electrical limits, protocol operation, and application implementation. Typical uses include industrial remote I/O, machine-control distributed interfaces, test equipment, building-control systems, and embedded control networks. The part is most appropriate when an existing CircLink host architecture can communicate with it and the PCB footprint matches the documented 48-pin package. A key procurement consideration is lifecycle and sourcing. Search results describe the family as active and show multiple distributor listings, but package-qualified alternatives were not established by the supplied cross-reference evidence. Engineers should therefore treat TMC2084-HT-E2 as a system-specific procurement choice rather than assume an interchangeable controller. This page consolidates verified manufacturer information, distributor availability evidence, technical comparison data, and procurement guidance. It distinguishes published facts from unavailable electrical details and avoids presenting unreferenced replacements as drop-in devices.
TMC22053KHC - Multistandard Video Decoder | onsemi
The onsemi TMC22053KHC is a multistandard digital video decoder in a 100-pin BQFP package. It accepts line-locked or subcarrier-locked composite, YC, or D1 digital video and produces digital component signals in multiple output formats. The device is designed for professional broadcast-video equipment that requires decoding and digital component processing within one integrated circuit. Its stated analog supply range is 4.75 V to 5.25 V, while the verified digital supply information is incomplete. A digital video decoder is an interface IC that converts legacy analog video signals into digitized component-video data. Within the product hierarchy, the TMC22053KHC is a video decoder, interface IC, signal-processing semiconductor, and integrated circuit. Decoder ICs sit between incoming video sources and downstream buffers, scalers, processors, transmitters, or digital recording equipment. They are commonly used in studio monitors, broadcast equipment, video switching systems, and professional capture products rather than ordinary consumer televisions. The TMC22x5y decoder family is presented as a broadcast-quality video-processing solution combining multistandard input acceptance with digital component generation. Supported input modes include composite, YC, and D1, and the outputs are available in several digital-component formats. This combination can reduce the number of separate conversion stages required in a professional video path. The exact supported output list, timing limits, resolution modes, and channel mapping require confirmation against the manufacturer datasheet. The KHC suffix identifies the supplied 100-BQFP package in the verified distributor records, and those records describe the component as active and intended for bulk packaging. The package provides 100 external leads for power, analog video, digital video, control, memory-interface, and synchronization functions. Exact pin assignments are not exposed in the supplied verified data, so a complete pinout cannot be reproduced without the manufacturer pinout diagram. TMC22053KHC fits studio television equipment, broadcast monitoring, professional video conversion, digital video routing, and embedded legacy-video acquisition systems. The principal design benefit is integration: accepting several input standards and producing digital component signals can simplify signal-chain partitioning when the downstream processor expects component video. System designers must still validate timing, sync polarity, colorimetry, blanking behavior, and interface voltage compatibility. The key engineering consideration is supply and interface planning. The analog core is specified for 4.75 V to 5.25 V, so layout must provide clean, stable rails and adequate decoupling. Digital-logic connections require confirmation of supply limits and voltage thresholds. PCB signal integrity also depends on keeping analog inputs away from switching-node and high-current return paths, while the large 100-lead BQFP requires careful fanout, ground-plane continuity, and via placement. This page consolidates the verified onsemi-family product description, distributor pricing, package information, comparison guidance, and practical integration notes. It distinguishes verified facts from parameters that still require confirmation from the datasheet, helping engineers source the part while avoiding unsupported assumptions about pinout, timing, compliance, or replacement behavior.
TMC22090R0C - RGB to NTSC/PAL Video Encoder | Fairchild
The Fairchild Semiconductor TMC22090R0C is an RGB-to-NTSC/PAL color-signal video encoder integrated circuit packaged in an 84-pin PLCC. The verified distributor record identifies the device as a video encoder IC that converts RGB signals into composite NTSC or PAL video, making it suitable for legacy analog-video equipment, industrial imaging systems, video test equipment, and signal-generation applications. Its 29.31 mm by 29.31 mm PLCC package is supplied in the R0C ordering configuration, and the listed distributor price is $13.8014 as of 2026-10-28. A video encoder is an interface IC that translates RGB color information into a composite analog video waveform accepted by displays, recorders, monitors, and broadcast-related equipment. The TMC22090R0C belongs to the broader integrated-circuit hierarchy of interface ICs, video signal-processing ICs, color encoders, and signal-conversion semiconductors. NTSC and PAL are legacy analog television color systems, so this component is primarily relevant to equipment that still supports composite-video interfaces rather than modern digital HDMI, DisplayPort, or camera-sensor interfaces. The verified product classification establishes RGB input, NTSC/PAL output, and the 84-PLCC package. Specific operating voltages, current consumption, clock requirements, synchronization behavior, input levels, output impedance, resolution limits, temperature range, and electrical performance ratings were not present in the supplied records. Those parameters must therefore be confirmed from the manufacturer datasheet before schematic capture, signal-integrity simulation, production release, or replacement qualification. The 84-pin PLCC package exposes substantially more external connections than a compact mixed-signal IC, suggesting a feature-rich legacy encoder implementation with multiple data, synchronization, control, power, and ground connections. Because the exact pin map and exposed-pad arrangement are unavailable in the verified data, engineers should not infer individual pin functions from the package count. The electrical connection must follow the official TMC22090 datasheet and its recommended application circuit rather than a generic PLCC footprint. Typical application areas include RGB-to-composite-video adapters, industrial monitor and control-panel interfaces, broadcast-equipment test fixtures, educational video laboratories, and repair or modernization systems that must preserve NTSC or PAL output. The device is also relevant where an existing system accepts analog composite video but produces RGB internally. Its usefulness depends on matching the source RGB timing, sync polarity, reference level, and target television standard to the encoder's documented operating conditions. A critical design consideration is that a correct package and function description does not guarantee an acceptable composite-video output. Input levels, blanking, synchronization, chrominance alignment, and output termination must be verified against the manufacturer specifications. PCB layout should follow the datasheet's routing and grounding guidance, and unused inputs should be handled according to the documented application circuit rather than by assumption. This page consolidates the verified distributor listing, current price reference, package information, product classification, sourcing links, and drop-in-replacement status for the TMC22090R0C. It also distinguishes documented facts from parameters that still require datasheet confirmation, helping engineers avoid unsupported assumptions when sourcing or designing around this legacy RGB-to-NTSC/PAL video encoder.
TMC22153AKHC - 10-Bit Multistandard Video Decoder | onsemi
The onsemi TMC22153AKHC is a multistandard digital video decoder and three-line adaptive comb decoder with 8-bit and 10-bit processing capability, supplied in a 100-pin MQFP package. The verified product information identifies the device as part of the TMC22153 three-line adaptive comb decoder family, where related versions support three-line, two-line, and band-split decoding architectures. A digital video decoder is an interface IC that reconstructs digital composite-video signals into component video data for subsequent processing. The TMC22153AKHC belongs to the broader video decoder and analog-to-digital signal-conversion hierarchy, combining multistandard input handling, adaptive comb filtering, and internal digital line stores. These features place it between an analog composite-video source and downstream display or video-processing circuitry. The principal identified advantages are adaptive comb-based decoding, support for multiple pin-compatible family configurations, 8-bit and 10-bit processing, and internal digital line stores. The internal line stores reduce the need for external memory when implementing the decoder's line-adaptive filtering functions. Multiple family versions also allow designers to evaluate different comb-filter architectures while retaining a common package-oriented design approach. Technically, the TMC22153AKHC is identified as the 10-bit member of its three-line decoder family in the verified search results. The available excerpts do not provide the complete input-format list, composite-video synchronization requirements, clock limits, supply voltage, output interface, or channel timing specifications. Those parameters must therefore be checked in the manufacturer datasheet before signal-integrity, synchronization, or PCB sign-off. Typical potential uses include legacy multistandard composite-video decoding, industrial video inspection, broadcast and studio signal conditioning, professional video equipment, and embedded systems that must convert composite video into a digital processing stream. The part's internal digital line stores and adaptive comb decoding make it relevant where comb filtering must be integrated without an external line-memory implementation. The primary design consideration is that a decoder replacement must match the exact family variant, package, pinout, clocking, voltage, and output timing. Related TMC22150, TMC22151, and TMC22152 devices may share family characteristics, but the verified excerpts do not establish every pin and parameter as identical. Original schematic capture, datasheet comparison, and hardware validation remain mandatory before substitution. This page consolidates the verified distributor, archive-datasheet, and cross-reference findings with explicitly marked specification gaps. It also distinguishes potentially related family devices from confirmed drop-in replacements, helping engineers identify sourcing options without presenting unverified compatibility as an established fact.
TMC22191R0C Digital Video Encoder | onsemi | Display Systems
The onsemi TMC22191R0C is an all-digital video encoder and layering engine that converts digital RGB or color-indexed graphics into programmable video timing and output signals. It supports 24-bit and 15-bit GBR/RGB 444 input formats, provides 30 color-indexed overlay colors for the TMC22191, and uses internal digital oscillators that eliminate the need for external crystals. Its programmable timing architecture makes it suitable for display-controller, graphics-processing, digital-video, and embedded visualization systems. A digital video encoder is an interface IC in the broader display and video-processing hierarchy. It accepts already-rendered pixel data, applies programmable timing and color or overlay functions, and produces output signals for downstream display or transmission circuitry. Unlike an analog encoder, the TMC22191R0C performs its processing entirely in the digital domain, helping preserve pixel data until the final output stage and reducing reliance on external synchronization components. Key features include support for 24-bit and 15-bit GBR/RGB 444 graphics inputs, 30 color-indexed overlay colors, fully programmable timing, and internal digital oscillators. The 15-bit input mode reduces interface width when full 24-bit color depth is unnecessary, while the 24-bit mode supports a wider color representation. The internal oscillators eliminate external crystal hardware when the application's timing can be generated digitally. The device is designed for systems that already supply synchronous digital graphics and require flexible video timing or layered overlays. Its all-digital architecture distinguishes it from solutions that perform color processing or regeneration through analog video stages. Exact electrical limits, supported output standards, operating temperature range, and package dimensions were not supplied in the verified source excerpts and must be confirmed from the full manufacturer datasheet before design release. Typical applications include industrial HMI panels, digital signage controllers, medical imaging interfaces, professional video equipment, instrumentation, and other embedded display systems. The 30-overlay capability is particularly useful when the source graphics must remain visible beneath cursor, menu, warning, or diagnostic information. A 15-bit interface can also simplify routing in cost-sensitive systems where 24-bit color depth is not required. Designers should allocate the TMC22191R0C according to its complete pinout and recommended interface schematic, including power, ground, pixel-data, timing, and output connections. Because the verified excerpts do not establish the exact package, exposed-pad requirements, pin numbering, or output electrical characteristics, those details should be checked directly in the manufacturer datasheet rather than inferred from distributor category labels. This page combines verified distributor availability, the documented input-format and overlay features, sourcing guidance, and explicit data gaps. It is intended to help engineers identify whether the TMC22191R0C matches an existing video-encoding design while separating confirmed facts from parameters that still require datasheet verification.
TMC2272AH5C3 - 36-Bit 50 MHz Colorspace Converter | onsemi
onsemi TMC2272AH5C3 is a digital colorspace converter with 36-bit color processing and 50 MHz throughput, provided in a 120-PPGA package measuring 34.16 mm by 34.16 mm. The converter processes three simultaneous 12-bit input and output channels, supports twos-complement input and output data, and provides overflow headroom in lower-resolution, user-defined coefficient modes. A digital colorspace converter is a specialized video-processing semiconductor that transforms pixel data from one color representation into another through programmable or fixed conversion coefficients. Within the broader video-processing IC category, its role sits between high-speed parallel input and output interfaces and downstream display, graphics, or video-processing systems. The TMC2272AH5C3 targets precision color conversion where multiple 12-bit channels must be processed simultaneously at high throughput. The principal operating characteristics include 36-bit color depth, three concurrent 12-bit channels, a 50 MHz processing rate, and a 20 ns pipelined throughput. The device can represent up to 64 Giga (2^36) colors. TTL-compatible inputs simplify interfacing with compatible digital video logic, while the simultaneous input and output architecture reduces the number of separate conversions required in multichannel graphics systems. Operationally, the converter accepts twos-complement digital data and applies user-defined coefficients for lower-resolution operating modes. This coefficient flexibility supports systems that need controlled color mapping rather than a fixed conversion matrix. The 20 ns pipeline is a timing-oriented feature: downstream logic can operate synchronously with a 50 MHz processing clock, subject to the timing constraints and setup requirements specified in the manufacturer datasheet. Typical uses include high-resolution graphics pipelines, broadcast video conversion, professional display equipment, medical imaging interfaces, industrial visualization systems, and multichannel color-processing equipment. Its three simultaneous channels are particularly relevant to RGB systems, where red, green, and blue data can be converted together rather than through separate serial or multiplexed processing stages. Designers should preserve the converter's parallel data timing, provide suitable input setup and output hold conditions, and account for the large 34.16 mm by 34.16 mm legacy PPGA footprint. PCB availability and replacement sourcing should be checked before new design commitments because the verified cross-reference search did not identify a confirmed pin-to-pin drop-in replacement. This product record consolidates the verified manufacturer-oriented description, distributor pricing and stock information, package details, known conversion features, and sourcing limitations. It also distinguishes confirmed characteristics from unverified parameters so procurement and engineering teams can evaluate this legacy video converter without relying on guessed specifications.
TMC424 - Triple Incremental Encoder Interface | Analog Devices
The Analog Devices TMC424 is a triple incremental encoder input interface IC that connects three incremental encoder channels to an SPI-compatible controller and is supplied in a 100-pin TQFP package. According to the manufacturer datasheet, it is especially useful with the TMC429 triple stepper motor controller for position verification or stabilization when additional software support is used. The TMC424 combines incremental encoder evaluation with serial host communication in one motion-control peripheral. An incremental encoder interface is a specialized integrated circuit that interprets A, B, and index signals from rotary or linear position encoders and converts those inputs into position data. In the broader device hierarchy, the TMC424 is an encoder interface IC, a motion-control interface, a peripheral integrated circuit, and ultimately a semiconductor. Its SPI-compatible connection allows position information to be transferred to a motion controller, DSP, or other embedded processor while keeping individual encoder lines from tying up host resources. The verified product information identifies three incremental encoder inputs and compatibility with SPI controllers. The manufacturer datasheet also identifies use with the TMC429 when position verification or stabilization is required. These features make the TMC424 suitable for stepper-motor positioning systems, CNC and automation equipment, robotics, and motion-control subsystems that need independent encoder feedback. The 100-TQFP package provides a compact surface-mount solution for multi-axis equipment. Because the verified excerpts do not expose the complete electrical timing table, operating limits, or exact pin names, those values remain marked as data needed rather than inferred. Engineers should use the official TMC424 datasheet for the complete register map, serial interface timing, electrical characteristics, pin assignments, and recommended application circuit. In a TMC429-based design, the TMC424 provides incremental feedback that can complement the controller's own motion functions. Additional firmware is required for the described position-verification or stabilization functions, so the host software must implement the relevant verification and correction behavior. This makes the TMC424 most appropriate where feedback improves reliability and where the three-axis architecture justifies the integration and software effort. PCB implementation should follow the manufacturer's pin and layout guidance exactly. The TQFP footprint requires adequate thermal and electrical layout quality, and encoder inputs should be routed away from noisy power and switching nodes. Because the supplied evidence confirms the package and functional role but does not provide the complete pinout, this page does not invent pin numbering or signal assignments. This product page synthesizes manufacturer documentation, distributor availability information, application context, replacement guidance, and engineering cautions. It separates verified facts from unavailable parameters, helping buyers identify the correct TMC424 while providing practical context beyond a basic distributor listing.
TMC8462A-BA - EtherCAT Slave Controller, 2x 100M PHY, 121-BGA | ADI
The Analog Devices (formerly Trinamic) TMC8462A-BA is a complete EtherCAT slave controller IC integrating two 100-Mbit PHYs, a dual switch-mode regulator power supply, and 24V-capable high-voltage digital I/Os, supplied in a 121-ball BGA package (9 mm x 9 mm). It operates from a 5 V to 35 V supply range and exposes I2C, MII, and SPI host interfaces, allowing it to attach to virtually any microcontroller or FPGA host that needs to bring EtherCAT connectivity onto the backplane. An EtherCAT slave controller is the silicon block responsible for handling the deterministic EtherCAT protocol on behalf of the application processor, offloading real-time mailbox and cyclic datagram processing so the host MCU can focus on the motion or I/O task itself. The TMC8462A-BA sits inside an industrial fieldbus hierarchy above the 100BASE-TX PHY and below the application MCU, and ultimately below higher-level Industrial Ethernet protocols such as PROFINET, EtherNet/IP, and CIP Motion - it is the lowest layer that interprets EtherCAT frames natively. Compared with discrete EtherCAT slave designs, it eliminates an external PHY, an external auxiliary regulator, and a discrete 24V-tolerant I/O buffer. Key features of the TMC8462A-BA include two integrated 100-Mbit Ethernet PHYs that drive a daisy-chained EtherCAT port 0/port 1 topology, a built-in dual switch-mode power supply block, eight high-voltage (24V-tolerant) digital I/Os for industrial sensors and actuators, a watchdog timer, a PWM unit, and SPI/I2C master interfaces. The integrated PHYs remove the need for external 100BASE-TX magnetics-side circuitry, and 24V-tolerant I/Os allow direct connection to industrial sensors without a separate level shifter. Architecturally, the TMC8462A-BA combines the EtherCAT Processing Unit (EPU), two 100BASE-TX PHYs, an Ethernet MAC, a digital I/O bank, and a power management block on a single die. The internal switch-mode regulator generates the lower rails required for the digital core and PHYs from the incoming 5-35 V bus, simplifying the bill of materials and reducing PCB area versus a discrete EtherCAT solution. Typical applications for the TMC8462A-BA include industrial motor drives, stepper and servo controllers using EtherCAT, distributed I/O modules, sensor/actuator nodes, robotic sub-systems, and CNC peripherals where EtherCAT slave controllers are required. It is also used as the slave side of the TMC8462A-EVAL evaluation kit. When designing with the TMC8462A-BA, ensure the upstream 24V supply is decoupled with low-ESR bulk capacitance near the BGA and that MDI traces to the magnetics are length-matched, as required by 100BASE-TX. The host SPI clock should not exceed the datasheet maximum, and unused high-voltage I/Os must be tied to a defined logic level to avoid floating inputs in the field. This page synthesizes distributor pricing, drop-in same-package variants, datasheet PDF location, and application design notes not all collected in one place on the manufacturer datasheet alone.
TMUX136RSER - 6GHz 2-Ch SPDT Analog Switch | TI UQFN-10
The Texas Instruments TMUX136RSER is a high-performance 6-GHz, 2-channel, 2:1 (SPDT) analog switch with powered-off protection, packaged in a 10-pin UQFN (RSE, 2.0 x 1.5 mm) and rated for a typical on-resistance of 9.5 ohm. It supports a wide VCC range of 2.3 V to 4.8 V and offers 1.4 pF typical on-state capacitance, making it ideal for high-frequency signal multiplexing. What is an analog switch/multiplexer? An analog switch (also called a multiplexer or MUX) is a solid-state semiconductor device that routes analog or digital signals between multiple input/output paths under digital control, using MOSFET transistors as the switching elements. Analog switches sit within the broader hierarchy of interface ICs -> signal routing -> semiconductor ICs. The 2:1 (SPDT) configuration means each of the two independent channels can connect a common pin to one of two possible inputs, a topology commonly used for signal multiplexing, source selection, and USB/MIPI/LVDS switching. Key features include a -3 dB bandwidth of 6 GHz, 1.4 pF on-state capacitance (Con), 9.5 ohm typical on-resistance (Ron), and 1.8 V-compatible control inputs that interface directly with low-voltage processor GPIOs. Power-off protection forces all I/O pins into high-impedance mode when VCC is removed, protecting downstream components and preventing back-powering through the signal path. The flow-through pinout places inputs and outputs on opposite sides of the package, simplifying PCB routing. The architecture uses N-channel MOSFET pass transistors driven by a charge-pump-assisted gate driver, which achieves low Ron flatness across the input signal range and supports bidirectional signal paths. The 6 GHz bandwidth enables pass-through of high-speed differential protocols such as USB 2.0, MIPI DSI/CSI, and LVDS without significant insertion loss. Typical applications include tablet and notebook signal multiplexing, smartphone MIPI/DSI switching, USB 2.0 high-speed signal routing, and audio signal path selection. The device also finds use in test equipment and instrumentation where high-bandwidth signal multiplexing is required. When designing with this device, observe the absolute maximum ratings for analog signal voltage. Use controlled-impedance PCB traces (typically 50 ohm single-ended or 90 ohm differential) for high-frequency signals to preserve signal quality at the rated 6 GHz bandwidth. This page synthesizes distributor pricing, drop-in alternatives from TI and competitors, and practical design notes not found in the manufacturer datasheet alone.
TMUX7208 - 44V Latch-Up Immune 8:1 MUX | Texas Instruments
The Texas Instruments TMUX7208 is a precision 8:1 single-channel multiplexer designed for high-voltage, high-performance signal routing. It operates from a single supply of 4.5V to 44V, dual supplies of ±4.5V to ±22V, or asymmetric supplies such as VDD=12V and VSS=-5V. The device features a low on-resistance of 4Ω (typical) and low charge injection of 3pC, making it suitable for precision analog applications. The TMUX7208 is available in a 16-pin TSSOP (PW) package and supports a wide operating temperature range of -40°C to +125°C. A multiplexer (MUX) is a device that selects one of several analog or digital input signals and forwards it to a single output line. The TMUX7208 is an analog multiplexer, specifically an 8:1 configuration, meaning it routes one of eight input channels to a common output based on the state of three address pins and an enable pin. This functionality is essential in data acquisition systems, test equipment, and industrial automation where multiple sensors or signals need to be sampled sequentially by a single ADC or measurement circuit. Key features of the TMUX7208 include latch-up immunity, which prevents damage from overvoltage or ESD events, and 1.8V logic-compatible inputs, allowing direct interface with low-voltage microcontrollers without level shifters. The device supports high current up to 300mA (max), making it robust for various loads. The low on-resistance and charge injection ensure minimal signal distortion and glitches during switching. The TMUX7208 uses a precision architecture with a break-before-make switching mechanism, preventing momentary shorting between channels. The device also features an enable pin that, when low, disconnects all channels, providing a high-impedance state. This is useful for power-down or isolation scenarios. The wide supply range and latch-up immunity make it ideal for industrial and automotive environments where voltage transients are common. Typical applications include data acquisition systems, test and measurement equipment, industrial process control, and battery monitoring systems. The TMUX7208 can be used to multiplex multiple sensor inputs into a single ADC, reducing component count and cost. Its high-voltage capability allows direct connection to 24V industrial buses without additional level shifting. When designing with the TMUX7208, ensure that the supply voltages are within the specified range and that the input signals do not exceed the supply rails. Proper decoupling capacitors on the supply pins are recommended to minimize noise. The address and enable pins should be driven with logic levels compatible with 1.8V to 5V, as the device is 1.8V logic compatible.
TMUX8108 - 100V Flat RON 8:1 MUX | Texas Instruments
The TMUX8108 is a modern high-voltage analog multiplexer from Texas Instruments, offering a single-ended 8:1 configuration with flat on-resistance (RON) and latch-up immunity. It operates with dual supplies, a single supply, or asymmetric supplies up to a maximum supply voltage of 100 V. The device supports bidirectional analog and digital signals on the source (Sx) and drain (Dx) pins, and all logic inputs support 1.8 V, 3.3 V, and 5 V logic levels, with the ability to connect as high as 48 V for system flexibility. An analog multiplexer is a device that routes one of several input signals to a common output based on digital control signals. In a single-ended 8:1 configuration, the TMUX8108 selects one of eight input channels and connects it to a single output. This functionality is essential in data acquisition systems, test equipment, and industrial automation where multiple sensors or signals need to be sampled sequentially by a single ADC or measurement circuit. The multiplexer acts as a signal router, enabling efficient use of expensive analog-to-digital converters and reducing component count. Key features of the TMUX8108 include a flat RON of 50 ohm, which minimizes distortion and ensures consistent performance across the input voltage range. The device provides latch-up immunity, preventing damage from overvoltage or overcurrent conditions. It supports a wide supply range up to 100 V, making it suitable for high-voltage industrial and automotive applications. The logic inputs are compatible with 1.8 V, 3.3 V, and 5 V systems, allowing direct interface with modern microcontrollers without level shifters. Technically, the TMUX8108 is built on a high-voltage CMOS process that enables low leakage currents and fast switching times. The flat RON characteristic is achieved through careful design of the switch architecture, ensuring that the on-resistance remains nearly constant across the entire analog input range. This reduces signal distortion and improves accuracy in precision measurement systems. The device also features break-before-make switching to prevent momentary shorting of channels during transitions. Typical applications include data acquisition systems, automated test equipment, industrial process control, and battery monitoring systems. In data acquisition, the TMUX8108 allows a single ADC to sample multiple sensor channels, reducing cost and board space. In battery monitoring, it can route individual cell voltages to a measurement circuit, enabling accurate state-of-charge estimation. The high-voltage capability makes it ideal for automotive 48 V systems and industrial 24 V or 48 V buses. When designing with the TMUX8108, ensure that the supply voltages are within the absolute maximum ratings and that the logic control signals are properly referenced to the logic supply. The device requires careful PCB layout to minimize parasitic capacitance and maintain signal integrity, especially in high-frequency applications. Additionally, consider the on-resistance and leakage current when calculating system accuracy, as these parameters affect the overall measurement error.
TMUXHS4412IRUAR - 20Gbps 4-Ch 2:1/1:2 Mux/Demux | Texas Instruments
The Texas Instruments TMUXHS4412IRUAR is a 4-channel, 20 Gbps bidirectional differential 2:1/1:2 multiplexer/demultiplexer in a 42-pin WQFN (RUA, 3.5 mm x 9 mm) package with exposed thermal pad, providing an 8 ohm on-state resistance and a typical -3 dB bandwidth of 13 GHz across each high-speed lane. The device supports USB 3.2 Gen 2x2, USB 3.2 Gen 1, USB 2.0, DisplayPort 1.4, SATA, PCIe Gen 3, SAS, and MIPI DSI/CSI by routing two differential sources to a single differential sink or vice versa with sub-130 ns propagation delay and 50 ps intra-pair skew. A high-speed multiplexer/demultiplexer (mux/demux) is a passive analog switch that selects one of multiple differential input pairs to a single output pair, enabling a host controller to share one PHY across two connectors, two PHYs across one connector, or to switch between redundant high-speed data paths. In the signal chain hierarchy the mux/demux sits between the protocol physical layer (PHY) and the connector, providing galvanic isolation between channels while preserving signal integrity at multi-gigabit NRZ and PAM3/PAM4 signaling rates. The TMUXHS4412 implements bidirectional switching so the same device serves either mux (2:1) or demux (1:2) topology without firmware configuration. Key differentiating features include 20 Gbps per-channel data rate (enabling USB 3.2 Gen 2x2 with two channels aggregated), 50 ps intra-pair skew, 8 ohm RON, 0.45 pF typical on-capacitance, sub-130 ns propagation delay, and dual supply support with 1.71 V to 1.98 V core and 3.0 V to 3.6 V I/O. The 42-pin WQFN (RUA) package provides a 31 C/W thermal pad-to-ambient resistance and supports -40 C to +105 C industrial operation. The architecture uses a pair of differential CMOS pass gates per channel with an integrated charge pump to maintain low RON across the full signal swing, plus on-chip termination resistors selectable through SEL pins. The bidirectional design means the same part handles both upstream and downstream switching, simplifying inventory and reducing PCB layout differences between mux and demux placements. Typical applications include USB Type-C port multiplexers, DisplayPort dual-mode source switching, PCIe lane failover, SATA port multipliers, and front-panel USB-C routing on motherboards, docking stations, and embedded computing platforms. The wide 3.0 V to 3.6 V supply range makes it compatible with both 3.3 V I/O rail and modern sub-1.8 V core supplies. When designing with the TMUXHS4412, route the high-speed differential pairs as 90 ohm differential impedance with length matching to within 5 mils, place decoupling capacitors within 2 mm of each supply pin, and solder the exposed thermal pad to a thermal land on a high-K board to maintain the full -40 C to +105 C temperature range without additional vias. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that are not consolidated in the manufacturer datasheet, including 8 ohm RON and 13 GHz bandwidth values verified from the TI TMUXHS4412 datasheet.
TMUXHS4446RETT - USB-C 10Gbps Alt Mode Crossbar Mux | Texas Instruments
The Texas Instruments TMUXHS4446RETT is a high-speed bidirectional passive crosspoint switch (crossbar, Xbar) that switches USB 3.2 Gen2 SuperSpeed and DisplayPort 1.4/2.1 (up to 10 Gbps UHBR10) signals over a USB Type-C interface, with 7-ohm typical on-resistance, a 6x4 mux configuration, and a 40-pin WQFN (6 mm x 3 mm) package with exposed pad. A crosspoint switch or crossbar mux is a switching matrix in which any input lane can be routed to any output lane, giving system designers complete flexibility in high-speed signal routing. In the USB Type-C ecosystem, crossbar switches sit between the SuperSpeed/sideband pins of the USB-C connector and a device's USB 3.2 or DisplayPort controller, resolving the orientation and alternate-mode ambiguity that the reversible Type-C connector introduces. As such, it belongs to the analog switch and multiplexer family within signal-switching ICs, sitting between the USB-C connector and the SoC in the system hierarchy. Key features include support for USB 3.2 Gen2 (10 Gbps) SuperSpeed lanes and DisplayPort 1.4/2.1 UHBR10 signaling, integrated low-speed SBU switching for DisplayPort auxiliary (AUX) channels, and a passive, bidirectional switch architecture that adds minimal signal degradation. The 7-ohm typical on-resistance minimizes insertion loss impact on high-speed differential pairs, helping preserve eye diagrams at 10 Gbps rates. Architecturally, the TMUXHS4446 is a passive FET-switch crossbar rather than an active redriver or retimer. This means it consumes minimal power, introduces no added latency, and does not regenerate the signal, so total channel budget must account for its on-resistance and capacitive loading. Passive switching makes it ideal when the host and device have adequate link budget and no equalization is required. Typical applications include USB Type-C docks and dongles that switch between USB 3.2 and DisplayPort alternate mode, notebooks and tablets routing DP 1.4/2.1 lanes to a USB-C port, monitors with USB-C inputs, and smartphone or mobile-compute platforms requiring USB-C orientation and alternate-mode switching. A key design consideration is that because the part is passive, total insertion loss across the connector, PCB traces, and switch must fit the USB 3.2 Gen2 or DP UHBR10 channel budget; keep routing short and impedance-controlled. Follow TI's datasheet layout guidance for the exposed-pad WQFN. This page synthesizes distributor pricing data, drop-in alternative analysis, and practical design notes that go beyond the manufacturer datasheet, giving engineers a single citable reference for the TMUXHS4446RETT.
TPS2371D - IEEE 802.3af PoE Power Interface Switch | TI
The Texas Instruments TPS2371D is an IEEE 802.3af-compatible power interface switch for Power over Ethernet powered devices, with an 8-pin SOIC package. It is designed for PoE powered-device front ends that require controlled power delivery from an Ethernet connection. The verified listing identifies the device as a specialized power interface switch with a nominal 48 V supply context, CMOS technology, eight terminals, and a 1.27 mm terminal pitch. A power interface switch is the input-side protection and power-management circuit between an Ethernet cable and a PoE powered device. Its role is to establish the power path, protect the downstream system from unsuitable input conditions, and support the current and voltage limits associated with legacy IEEE 802.3af PoE systems. In system terms, it belongs to the power-management IC hierarchy and the broader PoE interface ecosystem. The main verified characteristics are legacy IEEE 802.3af compatibility, operation in the PoE power domain, an 8-terminal surface-mount SOIC format, and a listed maximum operating temperature of 70 °C. The distributor record also identifies a 57 V-related comparison context, while the supplied Partstack result lists 48 V nominal voltage. These figures should be checked against the manufacturer datasheet before final design release because the search snippets do not provide the complete electrical characteristic table. Typical uses include PoE-powered IP cameras, network access points, VoIP phones, industrial Ethernet endpoints, and other powered devices connected through an Ethernet infrastructure. The device is appropriate when the design uses the legacy 802.3af power interface concept and the existing board uses the TPS2371D pin arrangement. It is not a generic USB power switch or a complete PoE PD controller; neighboring devices with similar package names may serve different voltage, current, or protection functions. For PCB implementation, place the switch close to the Ethernet input and power-entry components, maintain the datasheet-defined spacing for high-voltage copper, and provide the required input and output decoupling. Confirm absolute maximum ratings, operating voltage, current limit behavior, thermal conditions, and exposed-lead connections from the official TPS2371 documentation before applying it to a new design. This page consolidates verified distributor availability, manufacturer positioning, package information, procurement data, and design cautions for engineers evaluating TPS2371D replacements or PoE front-end implementations.
TPS2371DR - IEEE 802.3af PoE PD Interface | Texas Instruments
The Texas Instruments TPS2371DR is an IEEE 802.3af-compatible power interface switch for Power over Ethernet powered devices, with integrated hot-swap and power-distribution functions in an 8-pin SOIC package. It provides a PD detection signature, class 0-4 classification signature, precision undervoltage lockout, a 20-ms UVLO off-time delay, and programmable inrush-current limiting. A Power over Ethernet powered-device interface is the circuit that receives power through an Ethernet cable, identifies the attached load, negotiates its power class, and safely connects that power to the local system. In the power hierarchy, a PD interface sits between the PoE supply and the powered equipment’s DC/DC converter or load. It prevents an unsupported or improperly connected network port from receiving unsafe power. The TPS2371DR’s principal engineering benefits are its IEEE 802.3af compatibility, integrated protection, and autonomous interface operation. The device provides both detection and classification signatures, eliminating separate handshake circuitry in many conventional PoE PD designs. Its internal hot-swap MOSFET helps control connection transients, while the programmable inrush limit reduces the stress applied to downstream capacitance and power circuitry. The chip also uses precision UVLO thresholds to distinguish valid operating conditions and includes a defined 20-ms off-time delay after UVLO. That delay provides controlled recovery before the interface attempts another valid operating state. As an 8-SOIC surface-mount device, the TPS2371DR supports compact PoE endpoint designs without requiring a large connector-side or board-edge package. Typical uses include IP cameras, VoIP phones, wireless access points, network switches, powered network adapters, and other low- to moderate-power Ethernet endpoints. These products can use the TPS2371DR when IEEE 802.3af behavior and a conventional eight-pin PoE PD interface are required. For higher-power or newer PoE standards, designers should verify the exact PSE, PD, class, voltage, and protection requirements before selecting this legacy-compatible device. Layout should keep the Ethernet input and power-path nodes physically separated from sensitive downstream electronics, and it should provide appropriate copper area for thermal dissipation during sustained power transfer. Component values must follow the manufacturer’s reference design because the programmable inrush and protection network determine startup behavior. The interface also requires correct grounding and protection placement to avoid allowing transient current into sensitive ports. This page consolidates the verified manufacturer, distributor, pricing, lifecycle, and replacement information for TPS2371DR, while clearly separating confirmed specifications from unavailable electrical details. It also provides application guidance and drop-in alternatives where the available cross-reference evidence supports pin and package compatibility.
TPS25810ATWRVCRQ1 - Automotive 3A USB-C DFP Controller | TI
The Texas Instruments TPS25810ATWRVCRQ1 is an automotive USB Type-C downstream-facing port controller and power switch with digital cable compensation, a 3 A rated integrated USB power switch, and a 20-pin WQFN RVC package measuring 3 mm by 4 mm. It supports an operating temperature range of -40°C to 125°C and is positioned for automotive USB Type-C applications requiring integrated Type-C source control and power-path management. A USB Type-C DFP controller is an interface IC that coordinates USB Type-C connection orientation, advertises source capabilities, and manages the attached USB power path. Within the product hierarchy, it belongs to the USB Type-C controller class, then interface ICs, then semiconductor devices. By combining protocol control and a rated power switch in one package, the device can reduce the component count associated with automotive USB-C source ports while keeping connection and power-delivery functions together. The TPS25810A-Q1 family provides an integrated 3 A rated USB power switch, digital cable compensation, and Type-C source-controller functionality. Its automotive-qualified ordering designation identifies it for harsh operating environments. The 20-pin RVC WQFN package offers a compact surface-mount footprint, while the specified -40°C to 125°C range supports use across industrial temperature conditions common in vehicle electronics. Digital cable compensation is the principal differentiating function highlighted in the verified manufacturer materials. It allows the controller to address voltage-drop behavior associated with connected cables, helping the source side manage the electrical conditions of the USB Type-C link more effectively. The integrated switch also provides a defined current-handling point between the supply rail and the USB-C port, reducing the need for separate discrete protection and power-path elements in suitable architectures. Typical uses include automotive USB Type-C charging ports, vehicle infotainment connectivity, rear-seat accessory power, diagnostic interfaces, and USB-C service connections. The controller-and-switch combination is particularly useful where a compact source port is needed without allocating a separate Type-C controller and power switch. Vehicle designers must still verify connector requirements, cable current ratings, automotive qualification requirements, and system-level protection for every production design. When laying out the TPS25810ATWRVCRQ1, place the device and its required support components close to the USB Type-C connector and minimize high-current trace lengths. Validate connector, cable, and switch thermal performance under sustained load because a 3 A switch rating does not remove connector or wiring limitations. Confirm all pin functions against the current TI datasheet before layout release, as the verified excerpts do not provide the complete RVC pin map. This page combines the verified TI and distributor product information, package details, application guidance, and same-package replacement analysis for TPS25810ATWRVCRQ1. It also identifies engineering details that require confirmation from the full manufacturer datasheet rather than substituting assumptions for missing electrical, pinout, pricing, or compliance data.
TPS25810TWRVCRQ1 - 3A USB Type-C DFP Controller | Texas Instruments
Texas Instruments TPS25810TWRVCRQ1 is an automotive USB Type-C Rev. 1.2 downstream-facing port controller with an integrated 3 A power switch, load detection, and VCONN support in a 20-pin WQFN (RVC) package. The device is intended for USB Type-C source applications requiring configuration-channel control, port-attachment detection, and power-path switching. Its specified automotive operating-temperature range is -40°C to +105°C. A USB Type-C controller, also called a USB Type-C port controller, is a specialized interface IC that manages the configuration channel, commonly called CC, on a USB Type-C connector. Within the product hierarchy, it belongs to interface ICs and USB interface controllers. The downstream-facing-port role means the controller manages a port that supplies power and data-oriented Type-C behavior toward an attached upstream-facing port or cable. The TPS25810-Q1 family combines several functions in one device. It monitors the CC lines to determine when a Type-C attachment is present, integrates a power switch rated at 3 A, and includes load-detection capability. The verified product information also identifies VCONN functionality. When an electronically marked upstream-facing-port cable is attached, the controller can apply VCONN power to the cable's CC pin, supporting powered Type-C cables and attached accessories. The automotive grade distinguishes this orderable part from the commercial TPS25810 family option. The TPS25810TWRVCRQ1 is specified for -40°C to +105°C operation and uses the 20-terminal RVC WQFN package. The distributor listing identifies the package as 20-WQFN in a 3 mm by 4 mm footprint, while the manufacturer's ordering information identifies the package as WQFN (RVC). Typical uses include automotive USB Type-C charging ports, vehicle infotainment connections, USB Type-C docking interfaces, and downstream-facing ports that must identify attached accessories before enabling the power path. The integrated switch can reduce the external component count compared with a standalone Type-C controller and discrete power switch, although the final circuit still requires correct input protection, output discharge behavior, thermal layout, and connector wiring. Designers should follow the manufacturer's recommended application schematic and verify connector compatibility, CC pull-up or pull-down requirements, VCONN power limits, and exposed-pad soldering. Because the target is a downstream-facing-port controller, system-level USB data routing, host or device role implementation, and USB-PD policy must be confirmed against the complete product requirements rather than inferred from the controller alone. This page consolidates verified manufacturer and distributor information with package, interface-function, selection, and design guidance. It distinguishes documented facts from parameters that require confirmation from the full Texas Instruments datasheet, avoiding unsupported substitute, pinout, and pricing claims.
TPS25820DSSR - USB-C Source Controller, 1.5A VBUS | Texas Instruments
The Texas Instruments TPS25820DSSR is a USB Type-C source controller and integrated 1.5 A VBUS power switch with VCONN support, housed in a 12-pin WSON (DSS) package. The device is designed for USB Type-C source applications that require Type-C attach detection, source-role control, VBUS current limiting, and an integrated power path. According to the Texas Instruments product and distributor information, the TPS25820DSSR operates from a 4.5 V to 5.5 V supply range and supports an operating temperature range from -40 °C to 125 °C. Its USB Type-C source-controller function is intended to simplify implementation in adapters, chargers, docks, and other USB-C power-delivery products. A USB Type-C source controller is a specialized interface and power-management IC that manages the behavior of a USB Type-C port when the device acts as a source or downstream-facing port. The TPS25820DSSR combines USB Type-C source detection and contract logic with an integrated 1.5 A VBUS switch, allowing a system to supply power to a connected USB-C sink while protecting the port against excessive current. In the broader component hierarchy, it belongs to the USB interface IC and power-management IC families rather than being a general-purpose logic device or standalone discrete MOSFET. The primary headline specifications are a 4.5 V to 5.5 V operating supply range, integrated 1.5 A VBUS power-switch capability, and a 12-WSON DSS package. The package is only 12 pins and is suitable for compact power-adapter and peripheral designs. The operating temperature range of -40 °C to 125 °C supports use across consumer, industrial, and temperature-qualified equipment, subject to the complete manufacturer datasheet for electrical limits and qualification details. The device also provides VCONN support, which is important for applications that need controlled VCONN behavior. TPS25820DSSR is positioned as a simple USB Type-C controller rather than a full USB Power Delivery policy engine. The Texas Instruments product page describes it as a USB Type-C source controller with an integrated 1.5 A USB VBUS power switch, while the TPS25820 evaluation module provides reference circuitry for evaluating the controller. Designers should therefore verify the required USB Type-C behavior, sink advertisement method, VCONN implementation, and fault-handling requirements against the datasheet before finalizing a product architecture. Typical uses include USB-C wall adapters, charging cables and power modules, docking stations, laptop and tablet charging accessories, industrial USB-C power supplies, and compact USB-C peripheral designs. The integrated switch can reduce the number of external power-path components when the design requires a modest 1.5 A source capability. A designer selecting a higher-current USB-C source solution would need a different controller and power-switch architecture rather than assuming that TPS25820DSSR can deliver more than its specified 1.5 A. The principal design consideration is the relationship between the external USB-C connector, input supply, output power path, and the controller's internal protection functions. The input supply must remain within the verified 4.5 V to 5.5 V range, and layout should minimize high-current loop area between the switch, connector, and capacitors. Decoupling, current-limit behavior, VCONN routing, thermal performance, and the exposed-pad grounding requirements must be checked in the manufacturer datasheet and evaluation-module layout. This product summary combines verified manufacturer and distributor information, package and application context, comparison guidance, and practical implementation notes to help engineers evaluate TPS25820DSSR for USB Type-C source designs beyond a basic catalog description.
TPS65193RGER - Dual High-Voltage TFT-LCD Scan Driver | TI
The Texas Instruments TPS65193RGER is a dual high-voltage scan driver for amorphous-silicon-gate TFT LCD panels, providing high-voltage gate-line outputs from -28 V to 35 V in a 24-VQFN 4 mm x 4 mm package. Each scan-driver section accepts a logic-level CPV input and produces complementary CKV and CKVB outputs, while a logic-level STV input generates the high-voltage STVP output. A high-voltage scan driver is a specialized interface IC that transfers low-voltage timing commands from the host controller to the elevated voltages required by TFT gate lines. Its position in the display hierarchy is controller interface, then row-driver interface, then gate-line scan driver. This device does not process image data; instead, it supplies the high-voltage, charge-sharing waveforms that select and bias TFT rows. Key features include a 35 V high output-voltage level, an output swing down to -28 V, scan-driver output charge sharing, and four logic-level inputs. The 24-VQFN package measures 4 mm on each side, supporting compact display-module designs where connector count and board area are constrained. The RGER orderable designation identifies the 4 mm x 4 mm VQFN package configuration. Each high-voltage scan driver receives CPVx and generates two outputs, CKVx and CKVBx. A separate STV logic input produces the STVP output. Charge sharing reduces peak drive demand by transferring charge between the complementary outputs rather than driving each output as an isolated hard switch, helping lower switching loss in the gate-line drive network. Typical applications are amorphous-silicon TFT LCD modules, including small-panel monitors, portable instruments, industrial HMIs, test equipment, and control-system displays. The device is most appropriate where the panel requires negative off-level and positive high-level gate drive but does not require a separate source-driver solution from the same device. Designers must account for the -28 V to 35 V output range, provide suitable bypassing on the high-voltage supply rails, and validate output timing against the target TFT panel. Panel bias requirements, leakage into neighboring rows, and clock-edge placement determine whether the charge-sharing outputs provide adequate settling time. This page consolidates the verified manufacturer and distributor information, separates documented specifications from unavailable data, and provides application guidance and comparison considerations that are not presented as a substitute for the complete Texas Instruments datasheet.
TPS65195YFFR 8-Channel Display Level Shifter | TI
The Texas Instruments TPS65195YFFR is an 8-channel display power and level-shifting integrated circuit packaged in a 30-pin DSBGA. Distributor records classify the device as a video processing IC and an 8-channel level shifter, placing it within the display-interface and video-signal-conversion segment of integrated-circuit applications. Its defining verified characteristics are the eight-channel architecture, display-oriented level-shifting function, and compact 30-DSBGA package. Detailed electrical ratings, supported logic standards, voltage limits, timing values, and thermal limits were not included in the supplied source material and therefore require confirmation from the manufacturer datasheet before schematic or layout release. A display level shifter is an interface IC that translates signals between voltage domains that use different electrical thresholds. This allows a host processor, graphics engine, or display controller to communicate more reliably with display-panel circuitry when input and output levels are not directly compatible. In the broader semiconductor hierarchy, the TPS65195YFFR belongs to interface ICs and, more specifically, to video interface ICs. Its eight channels allow multiple display-related signals to be handled within one package, reducing the component count compared with discrete translators. The verified distributor listing identifies the part as an 8-channel level shifter in a 30-pin DSBGA. This combination can be valuable in compact display modules where board area is constrained and several voltage-domain crossings are required. The BGA form factor also supports dense routing, although it demands assembly processes capable of handling fine-pitch balls. Package dimensions, ball pitch, exposed-pad details, soldering profiles, and reflow requirements must be taken from the official package drawing rather than inferred from the distributor description. Typical design use is a display controller interface, an LCD panel bias or signal interface, and a compact embedded display module. These uses follow from the verified display power and level-shifting classification; the supplied data does not enumerate supported panel interfaces or timing standards. Engineers should therefore treat the TPS65195YFFR as a display-interface candidate, not as a complete or independently characterized video processor, until channel direction, signal type, voltage ranges, and timing constraints are verified. A key implementation consideration is validating every connected display signal against the manufacturer's absolute-maximum and recommended operating limits. Because no pinout was supplied in the verified results, no pin assignments are asserted here. The official datasheet and land-pattern information must be used to confirm signal direction, supply pins, ground pins, and unused-ball handling before PCB routing begins. This page consolidates the verified distributor identity, package, and sourcing information with a structured engineering workflow for datasheet validation, alternative qualification, and display-interface design. It distinguishes confirmed facts from unavailable parameters rather than filling gaps with guessed electrical values.
TPS65197RUYR - 8-Channel LCD Level Shifter | Texas Instruments
The Texas Instruments TPS65197RUYR is an 8-channel level-shifter IC for LCD display applications, packaged in a 28-pin WQFN (RUY) package measuring 4 mm by 4 mm. It supports 2-channel and 3-channel charge-sharing methods, normal level-shifting operation, and panel discharge to VGH during shutdown. The device is designed to translate timing-controller logic-level signals into the higher gate-level signals required by gate-in-panel (GIP) LCD panels. TPS65197RUYR belongs to the interface IC and display-driver ecosystem. A level shifter is an interface IC that translates voltage domains while preserving signal timing and logic function. In an LCD system, the timing controller operates at lower logic voltages, while GIP row and column driver circuits may require elevated panel voltages. The TPS65197 provides eight channels for this signal conversion and supports panel-specific charge-sharing sequences that help control panel charging and discharge behavior. The principal feature set includes eight level-shifting channels, support for no-charge-sharing, 2-channel charge-sharing, and 3-channel charge-sharing operation, and a dedicated panel-discharge function. The manufacturer product page identifies the device as an 8-channel level-shifter supporting 2-channel and 3-channel charge-sharing and panel discharge in the WQFN (RUY) package with 28 pins. Because GIP panels can accumulate charge and generate transient loads during startup, the charge-sharing architecture is important. The supported operating modes let a system select a charging strategy according to panel timing requirements rather than using a simple fixed level translation approach. The shutdown discharge path provides a defined mechanism for returning panel nodes toward VGH during power-down. Typical uses include notebook computer LCD panels, desktop monitors, television panels, and other GIP-based display systems. The device is most appropriate when the source logic levels, panel gate-drive levels, supported charge-sharing sequence, and shutdown behavior must all be evaluated together. A replacement should not be selected solely by channel count; the timing of each output, panel discharge behavior, voltage ratings, and board footprint must be confirmed against the original design. This page combines the verified manufacturer description, distributor package information, drop-in alternatives, and engineering-oriented design guidance. The 28-pin WQFN footprint, exposed thermal pad, high-speed panel signals, and power-sequencing requirements should be reviewed against the complete manufacturer datasheet before layout or replacement qualification.
TPS65198RUYR - 13-Channel LCD Level Shifter | Texas Instruments
The Texas Instruments TPS65198RUYR is a 13-channel level shifter with an integrated operational amplifier for LCD televisions and monitors, supplied in a 28-pin WQFN (RUY) package measuring 4 x 4 mm. It supports an operating temperature range of -40 C to +85 C and is designed for display-interface applications where multiple voltage domains and signal buffering are required. A level shifter is an interface IC that translates logic signals between voltage domains whose high and low thresholds differ. In an LCD television or monitor, source electronics, timing controllers, panel interfaces, and backlight systems may operate from different supply rails. A multi-channel level shifter allows those signals to cross between incompatible voltage domains, while the integrated operational amplifier provides buffering for a signal that requires drive or amplification. The TPS65198RUYR's 13-channel architecture consolidates multiple translated logic connections in one package. This can reduce the number of discrete level-shifter components and simplify printed-circuit-board layout compared with a collection of individual translators. Its 4 x 4 mm WQFN format also supports compact display-control designs where connector density and panel-interface routing leave limited board area. The verified operating temperature range is -40 C to +85 C, covering industrial temperature conditions commonly encountered in display electronics. The available LCSC listing identifies an 8 V to 20 V supply-related value, but the provided source excerpt does not clearly identify that parameter or its test conditions; consequently, voltage limits, channel direction, translation thresholds, and the integrated amplifier's electrical ratings require confirmation in the manufacturer datasheet before design release. Typical uses include LCD monitor panel-interface circuits, television timing and control boards, display power-sequence logic, and other multi-rail display systems where a compact level-translation stage is needed. Because this device combines translation and amplification, it can simplify signal-interface design when the source impedance and loading requirements of the translated channels differ. Engineers should confirm every channel's direction, voltage domain, enable behavior, and the exposed-pad connection directly against the TI datasheet and the PCB footprint. The 28-pin WQFN package is also thermally and assembly sensitive; proper land-pattern compliance, paste control, and exposed-pad soldering are required for reliable production yield. This page consolidates the verified manufacturer identification, distributor package data, temperature rating, and supply-range excerpt for TPS65198RUYR, while clearly separating missing electrical data from confirmed values. It also documents the absence of a manufacturer-verified drop-in substitute rather than presenting an unverified package conversion as a drop-in replacement.
TPS65198RUYT - 13-Channel Level Shifter | Texas Instruments
The Texas Instruments TPS65198RUYT is a 13-channel level shifter with an integrated operational amplifier for GIP-based LCD television and monitor applications, packaged in a 28-pin WQFN (RUY) 4 x 4 mm package. It accepts five timing-controller input signals, uses an internal state machine to generate twelve output signals, and combines level shifting with op-amp signal conditioning. Its specified operating-temperature range is -40°C to +85°C. A level shifter is an interface device that translates logic-voltage levels so circuits using different voltage domains can communicate reliably. In this application, the TPS65198 belongs to the display-driver interface hierarchy: logic level translation, display timing-interface conversion, voltage-domain interfacing, and display-driver ICs. Its integrated op amp provides an additional analog signal-conditioning function alongside the digital level-shift outputs. The principal feature is the combination of a 13-channel level-shifting architecture, five external inputs, twelve internally generated outputs, and op-amp integration. This consolidation can simplify the circuitry associated with GIP panel timing control. The built-in state machine sequences the generated outputs according to the panel-interface requirements, while the integrated amplifier can support signal conditioning where the timing interface requires amplification or level adjustment. TPS65198RUYT is intended for LCD TVs and monitors using GIP technology, where multiple panel signals must be shifted between source-driver, gate-driver, and timing-controller voltage domains. The 4 x 4 mm WQFN package supports compact display-controller boards, but its exposed thermal-pad construction requires careful PCB layout for electrical return paths and heat spreading. Designers should also account for the high-speed edge behavior of the interface when routing signals and selecting input and output impedance. Typical uses include large-panel LCD television timing control, LCD monitor panel interfaces, and other GIP display systems that require coordinated multi-channel level translation. Because the verified source set identifies a 28-pin WQFN package and a -40°C to +85°C range, the device is appropriate for industrial and consumer display environments requiring operation across that temperature span. The principal design consideration is to follow the manufacturer datasheet exactly for exposed-pad connection, decoupling, signal routing, and output-state sequencing. Place input and output return paths close to the device, provide the specified supply and bypass capacitance, and avoid introducing stubs on timing signals. Verify every panel connector voltage domain and the state-machine timing before releasing a display board. This page consolidates the verified manufacturer and distributor information, distinguishes a true drop-in replacement from a packaging-only ordering variant, and highlights application-specific design considerations that are not apparent from a basic distributor listing.
TPS66021YBGR - 20V Sink, 5V Source USB-C Switch | TI
The Texas Instruments TPS66021YBGR is a one-channel integrated USB-C Power Delivery source-and-sink power multiplexer with a 20V sink path, a 5V source path, and a 5V dead-battery VBUS LDO, housed in a 28-ball DSBGA package measuring 1.61 mm by 2.81 mm. It combines two directional power paths in a compact device intended to manage charging, powering, and protection around a USB-C connection. A USB-C power-path multiplexer is a specialized power-management integrated circuit that controls current between a connector and internal supply rails. It belongs to the hierarchy power multiplexer, power-path controller, power-management IC, and semiconductor. By combining source and sink switching, it can route external VBUS power into a system, provide regulated 5V power from an internal source, and isolate paths during faults or operating-mode changes. The verified manufacturer data identifies a 4V-to-22V sink power path and a 5V source path. The source path enters constant-current operation when its load exceeds the selected current-limit threshold. Each path includes overtemperature and reverse-current protection, while the family supports a fault indication for overcurrent and overtemperature events. The integrated high-voltage VBUS LDO provides 5V for this device and other system components under dead-battery conditions. The TPS66021 integrates a 20V USB-C sink capability and 5V source capability rather than acting only as a passive analog switch. Its VBUS-side architecture allows the system to distinguish and control external power conditions, while the source path supplies a defined output level. The fault function gives the host circuitry a signal when protection circuitry has detected an abnormal event, enabling controlled shutdown or fault recovery. Typical uses include USB-C laptop and tablet power adapters, portable equipment, battery-powered industrial products, and compact systems that must accept external USB-C power while retaining a safe internal 5V supply. The integrated source, sink, and dead-battery functions can reduce board area compared with a discrete switch network. Designers must still validate connector orientation, CC behavior, capacitor selection, current limits, thermal performance, and system power sequencing against the full manufacturer documentation. For PCB layout, follow the manufacturer package land pattern and place high-current input, output, and ground connections with short, wide paths. Place required input and output capacitors close to their associated balls and keep sensitive control and fault traces away from high-di/dt power loops. Verify the selected current threshold, startup behavior, and fault response in the final USB-C system. This page consolidates verified manufacturer descriptions, distributor availability, package information, replacement evidence, and application guidance. It also distinguishes confirmed facts from parameters that require the complete datasheet, preventing unsupported electrical or compliance assumptions during design review.
