TMC22191KHC - Digital Video Encoder | onsemi | NTSC/PAL
onsemi TMC22191KHC is an all-digital video encoder and layering engine that converts RGB, YCbCr, color-indexed, or CCIR-601 image data into analog NTSC or PAL composite and Y/C video outputs. The device accepts 24-bit and 15-bit GBR/RGB 444 formats, supports 30 overlay colors for the TMC22191, and uses internal digital oscillators, so external crystals are not required. It is supplied in a 100-MQFP package measuring 20 mm by 14 mm. A digital video encoder is a signal-processing integrated circuit that translates digital graphics or image data into conventional analog television signals. Within the broader semiconductor hierarchy, the TMC22191KHC belongs to the video encoder, interface IC, and signal-conversion markets. Its function connects a digital video source, such as a graphics controller or embedded display system, to displays or video equipment that accept composite or Y/C analog input. The encoder matrixes accepted digital image data into luminance and chrominance components. Its digitally synthesized chrominance subcarrier is then modulated onto the color information, while separate interpolation paths process the luminance and chrominance signals at twice the pixel rate. Dedicated 10-bit D/A converters convert the digital video information into analog output levels, allowing simultaneous composite and Y/C S-VIDEO generation without external component selection or tuning. Programmable timing supports adaptation to different input and television formats. According to the manufacturer datasheet information, the TMC22x91 family is compatible with SMPTE 170M NTSC and CCIR Report 624 PAL television standards, as well as PAL-M and NTSC-without-pedestal operation. The TMC22191 also supports a 30-color indexed overlay function, making it useful when graphics and text must be combined with a base video source. Typical uses include industrial panel computers, video test equipment, digital signage, CCTV monitor interfaces, broadcast-production equipment, and embedded graphics systems requiring analog NTSC or PAL compatibility. It is particularly useful where an existing analog display remains in the design but the image source is digital and generated entirely in hardware. Designers should verify the complete input timing, output standard, synchronization requirements, and analog output loading against the manufacturer datasheet before layout. PCB implementation requires careful routing of digital inputs and analog outputs, stable supply distribution, and suitable grounding. The video outputs should also be evaluated for the required termination, filtering, impedance, and connector routing of the target display. This page combines verified manufacturer and distributor information with practical application guidance, comparison details, and purchasing data as of 2026-10-28. It also records where pin-level, electrical, lifecycle, and substitute-part information was not established by the supplied sources.
TMC2242AKTCT - 30MHz Half-Band Digital Filter | onsemi
The onsemi TMC2242AKTCT is a digital half-band interpolating and decimating filter with a 30 MHz cutoff or center frequency, 12-bit or 16-bit operation, and a 44-MQFP 10 mm by 10 mm package. It operates from a 4.75 V to 5.25 V supply. The device is designed for digital multimedia signal-processing applications where a half-band filter is required for efficient interpolation or decimation without requiring a full general-purpose FIR-filter implementation. A half-band filter is a specialized FIR digital filter whose frequency response has a narrow transition band centered near the cutoff frequency. Only every other input coefficient is nonzero in the ideal half-band structure, reducing the number of active multipliers relative to a conventional FIR filter. In signal-processing hierarchies, the TMC2242AKTCT belongs to the active-filter and digital-filter categories, then to the interface-IC and video-IC application segment. The TMC2242AKTCT provides one filter, a nominal 30 MHz cutoff or center frequency, and digital operation identified as 12-bit or 16-bit. Its specified 4.75 V to 5.25 V supply range is suitable for conventional 5 V digital signal-processing equipment. The 44-MQFP surface-mount package provides 44 physical pins and a 10 mm by 10 mm footprint. Active-production status is reported by Rochester Electronics in the supplied distributor information. The device combines interpolation and decimation in one digital filter family. When used for interpolation, it can increase the effective sample rate while suppressing imaging between original signal bands. When used for decimation, it can reduce the data rate while suppressing aliasing before the signal is downsampled. The half-band coefficient structure is particularly useful where computational efficiency, predictable filtering, and a compact implementation are more important than a user-programmable coefficient architecture. Typical applications include digital video interfaces, multimedia processing chains, communications equipment, audio and video sample-rate conversion, clocked digital filtering, and embedded signal-processing systems. The component can be placed after an ADC or digital transmitter when decimation is required, or before a DAC or digital transmitter when interpolation is required. System timing, input word width, output word width, and clock polarity must be verified against the manufacturer datasheet before layout is finalized. The primary design consideration is clock and data-interface validation. The 5 V operating range is narrow, so supply regulation, ground return paths, and exposed-pad connection must follow the manufacturer layout recommendations. Because the provided search results do not expose the complete pin table, clock timing, control-signal truth table, or thermal-resistance data, engineers should confirm those details in the Fairchild Semiconductor manufacturer datasheet before production release. This product record consolidates verified distributor pricing, package information, lifecycle information, technical-fit guidance, and traceable source links. It also distinguishes what is confirmed from what still requires datasheet verification, providing a practical basis for schematic capture, PCB planning, sourcing, and prototype review without presenting unavailable electrical details as guaranteed specifications.
TMC2272AH5C2 - 36-Bit 50 MHz Color Converter | Fairchild Semiconductor
Fairchild Semiconductor TMC2272AH5C2 is a 36-bit digital colorspace converter with 50 MHz throughput, three simultaneous 12-bit input channels, and three simultaneous 12-bit output channels in a 120-pin plastic PGA package measuring 34.16 x 34.16 mm. It processes three 12-bit color components in parallel and supports 10-bit user-defined two's-complement fractional coefficients. A digital colorspace converter is a signal-processing IC that transforms color-component data using programmable arithmetic coefficients. In the product hierarchy, it is an interface IC, a video-processing IC, and ultimately a digital signal-processing semiconductor. The converter can support programmable color correction, matrix conversion, and related RGB-component transformations when its coefficient ports are driven by an external control system. The TMC2272AH5C2 provides 50 MHz operation, corresponding to a 20 ns pipelined throughput. Its three 12-bit input ports accept two's-complement integer data, while its three 12-bit output ports use the same numeric format. This arrangement allows three simultaneous 12-bit channels and a combined 36-bit color word. User-defined coefficients are represented as 10-bit two's-complement fractional values. The device supports TTL-compatible inputs and provides overflow headroom when it is operated at lower numerical resolution. The overflow-headroom feature is useful when intermediate calculations require additional range beyond the selected output resolution. Pipeline architecture supports sustained parallel data processing rather than requiring the converter to wait for a full multi-channel operation before accepting another input set. Typical applications include RGB color-space transformation, programmable video color correction, digital imaging pipelines, broadcast video processing, and industrial vision systems requiring three parallel color channels. The 36-bit parallel interface and 50 MHz pipelined operation suit systems that convert three-component color data between numeric spaces without introducing a serial protocol bottleneck. PCB design should account for the large 120-pin PGA footprint, high pin count, and numerous data and coefficient connections. Designers should follow the manufacturer's pinout and recommended decoupling guidance directly because the supplied web results do not expose a complete verified pin list, power requirements, or recommended component layout values. This page combines the verified 50 MHz throughput, 36-bit color width, three-channel I/O architecture, 10-bit coefficient format, package information, distributor availability, and cross-reference findings with practical design guidance. It also distinguishes confirmed operating facts from parameters that still require confirmation from the original manufacturer datasheet.
TMC2272AH6C - 50MHz 36-Bit Video Converter | onsemi
The onsemi TMC2272AH6C is a 50 MHz, three-channel, 36-bit digital colorspace converter and color-correction IC with simultaneous 12-bit input and output channels, supplied in a 120-pin ceramic PGA package. The device provides 20 ns pipelined throughput, uses nine parallel multipliers to process imagery in real time, and supports twos-complement input and output signals. Its 36-bit processing path represents three 12-bit color components, while user-defined coefficients can be selected at 10-bit resolution. TTL-compatible inputs, overflow headroom in lower-resolution modes, and a 4.75 V to 5.25 V supply range place the converter in the digital video signal-processing category. A digital colorspace converter is an interface IC that transforms sampled image data between color spaces or applies correction coefficients to three color channels. In the signal-processing hierarchy, this function belongs to digital video ICs, interface ICs, and ultimately broader semiconductor and signal-processing device categories. Unlike a simple parallel interface, the TMC2272A family combines parallel pixel data, arithmetic color correction, and pipelined throughput in one device intended for real-time camera, monitor, and image-processing systems. The principal features begin with a 50 MHz operating rate, corresponding to 20 ns pipelined throughput. Three 12-bit channels can be handled simultaneously, producing a total 36-bit processing width. Nine parallel multipliers support the color-conversion arithmetic, while 10-bit user-defined coefficients provide programmable correction. TTL-compatible input signaling simplifies interfacing with compatible parallel video logic, and lower-resolution operating modes include overflow headroom to accommodate wider internal calculation ranges. The part operates from a 4.75 V to 5.25 V supply, placing it in a conventional 5 V digital logic environment. Its three parallel 12-bit paths are processed through a pipelined architecture rather than through a serial link. This parallel, deterministic structure is suited to systems that already represent video as component data and require high-rate color transformation or correction without converting the stream to a serial interface. The 120-pin ceramic PGA package provides the numerous external connections expected for three wide parallel channels and associated control signaling. Typical uses include digital camera color correction, monitor and display processing, broadcast video conversion, machine-vision preprocessing, and real-time image analysis. In these systems, the converter can sit between a parallel image sensor or frame buffer and downstream display or processing logic, applying programmable channel coefficients before the 12-bit components reach their destination. The 50 MHz rate supports high-throughput real-time pipelines, while the simultaneous three-channel architecture avoids separate converters for individual color components. Designers should verify the complete pinout, timing requirements, coefficient programming procedure, and supported output encoding against the manufacturer datasheet before layout. Parallel 36-bit data paths require careful bus-length matching and grounding, and unused digital inputs should be handled according to the device instructions. Because the verified evidence does not provide a public manufacturer-hosted PDF or a complete electrical table, design values not explicitly stated in the available source material should be confirmed during engineering review. This page consolidates the verified 50 MHz throughput, 36-bit conversion, 5 V supply, package, sourcing, and technical-paper details into one engineering-oriented record. It also clearly separates confirmed characteristics from unresolved package timing, pin assignment, lifecycle, and replacement data, helping engineers evaluate the TMC2272AH6C without inferring unsupported specifications.
TMC2272AKEC2 - 50MHz 36-Bit Video Converter | onsemi
onsemi TMC2272AKEC2 is a digital colorspace converter IC with 36-bit color processing, a 50 MHz clock, and pipelined throughput in a 120-pin MQFP package measuring 28 mm by 28 mm. The converter supports three simultaneous 12-bit input and output channels, providing 36 parallel color bits for professional video-processing systems. Its 50 MHz operating rate corresponds to a 20 ns pipeline period, while two’s-complement input and output formats simplify signed digital video calculations. A digital colorspace converter is a specialized signal-processing IC that transforms color data between component spaces or performs programmable matrix operations on digital RGB or luminance-chroma signals. Within the broader semiconductor hierarchy, it belongs to the video-processing IC and interface-IC categories rather than analog amplifiers or general-purpose logic. Such converters are used when a video system needs controlled transformation of color coordinates, channel weighting, or matrix coefficients before display or downstream processing. The TMC2272AKEC2 provides three simultaneous 12-bit channels at both the input and output, supporting the full 36-bit word width in one pipeline stage. It also supports lower-resolution operation with user-defined coefficients, with overflow headroom available in those modes. TTL-compatible inputs simplify interfacing with compatible digital video logic, while the pipelined architecture supports sustained 50 MHz operation without changing the external 120-MQFP footprint. The part is identified as a linear video-processing IC and is distributed as TMC2272AKEC2 by onsemi. Distributor records also associate the device with Fairchild Semiconductor and Raytheon part records, reflecting its commercial lineage rather than a different device function. The EC2 ordering suffix appears in the exact MPN retained by current distributor listings, and the supplied records identify the physical package as 120-MQFP, 28 mm by 28 mm. Typical uses include broadcast and professional video infrastructure, digital color processing, luminance-to-chroma or RGB matrix conversion, test equipment, and embedded video systems that need simultaneous signed 12-bit channel arithmetic. Because the converter is digital, performance depends on clocking, input-output timing, coefficient configuration, and termination discipline rather than analog gain settings. The 50 MHz pipeline rate supports high-volume pixel processing while limiting data buffering requirements in multi-stage video paths. Designers should treat the datasheet as the controlling source for pin assignments, timing, coefficient tables, and electrical limits because those details were not included in the supplied verified records. The three channel groups should be routed with matched impedance, clocks should remain clean, and unused signals should follow the manufacturer’s termination and grounding guidance. The MQFP package also requires careful lead inspection and adequate board cleanliness because its closely spaced leads can complicate assembly and rework. This product page combines the verified 50 MHz, 36-bit, three-channel, and package details with distributor pricing, sourcing links, application guidance, and replacement constraints. It also distinguishes verified orderable alternatives from unsupported package or timing substitutions so engineers can make a traceable procurement decision rather than relying on a generic cross-reference match.

Texas Instruments TPS25810RVCR is a USB Type-C downstream-facing port source controller with an integrated 3 A power switch, VCONN support, and load detection, supplied in a 20-pin WQFN RVC package. The device is intended for USB Type-C host ports and supports an operating supply range of 4.5 V to 6.5 V over a -40 °C to 125 °C temperature range. Its integrated switch reduces the number of separate power-path components required in a Type-C source design. A USB Type-C source controller is an interface IC that manages the behavior of a USB Type-C downstream-facing port. It coordinates source-side power delivery, supports the VCONN supply used by powered accessories and cables, and can include load-detection functions. In the broader hierarchy, the TPS25810 belongs to the USB Type-C interface-controller family within interface ICs and broader power-management and connectivity systems. The primary specifications visible in the verified manufacturer and distributor data identify the part as a 3 A USB power switch and USB Type-C source controller. VCONN support allows the system to provide a controlled auxiliary supply to compatible USB Type-C accessories. Load detection provides the controller with information for evaluating the connected load. The RVC package contains 20 pins and uses surface-mount construction. The TPS25810RVCR is specified for a 4.5 V to 6.5 V operating supply range, making it suitable for systems that derive their operating rail from a 5 V USB or power-management subsystem. The manufacturer part-details data identifies a -40 °C to 125 °C operating-temperature range. This combination supports consumer, industrial, and embedded USB Type-C host implementations where a compact integrated source path is valuable. Typical applications include USB Type-C downstream-facing ports in docking stations, laptop accessories, monitors, industrial HMI panels, power adapters with Type-C outputs, and embedded USB-C charging or connectivity ports. In a typical implementation, the controller interfaces with the USB Type-C connector and system logic while the integrated 3 A switch controls the source power path. Designers should verify the connector, cable-current rating, VCONN load limits, thermal performance, and all protection requirements against the manufacturer datasheet before releasing a production PCB. The verified search data does not expose the complete pin table, electrical limits, timing values, or detailed application circuit, so those values should not be inferred from the distributor summaries. This product page consolidates verified manufacturer, distributor, and cross-reference information with practical selection guidance and engineering caveats. It distinguishes documented capabilities from unavailable technical details and avoids presenting unverified performance figures as manufacturer specifications.
TPS65190RHDR - 10-Channel LCD Level Shifter | Texas Instruments
The Texas Instruments TPS65190RHDR is a 10-channel bidirectional voltage level shifter and VCOM buffer for large-format LCD displays, housed in a 28-pin VQFN (RHD) package measuring 5 mm by 5 mm. The device provides separate positive-supply groups for the level-shifter channels, uses a common negative gate-line supply, and includes an operational amplifier for generating or buffering the LCD VCOM reference. Its specified operating-temperature range is -40°C to +85°C. According to the manufacturer product page, both positive supplies can be tied together when one positive supply voltage serves all channels. A voltage level shifter is an interface IC that translates logic-signal voltage ranges between two electrical domains. The TPS65190 belongs to the level-shifter and LCD-driver hierarchy, where the level-shifter channels support TFT-LCD source and gate-driver interfaces while the VCOM buffer conditions the common LCD reference voltage. Integrating these functions in one device reduces the number of separate interface components required in a display timing-control system. The primary feature is support for 10 level-shifter channels in a compact 28-VQFN package. Texas Instruments describes low-impedance output stages that provide fast rise and fall times even when driving significant capacitive loads. Two independently supplied positive voltage groups allow the display interface to operate with different positive supply levels, while both groups share the negative VGL supply. This architecture provides flexibility when source-driver and gate-driver circuitry use different voltage requirements. The TPS65190 also integrates a VCOM operational amplifier. VCOM is the common reference applied across LCD pixels and must remain stable for correct display contrast and image quality. Buffering VCOM near the display timing-control electronics helps isolate the reference from source impedance and load transients. The VQFN package provides a high pin count for ten data paths, power connections, ground returns, and the VCOM buffer while remaining suitable for compact large-format display designs. Typical uses include LCD televisions, computer monitors, industrial panel displays, digital signage, and other large TFT-LCD systems. The device is particularly relevant when a display controller uses voltage levels different from those required by the panel gate and source drivers. System design must account for trace capacitance, channel timing, supply sequencing, and the voltage ranges supported by the connected display drivers. When laying out the PCB, place the device near the interface between the timing controller and LCD panel, minimize routing between level-shifter outputs and panel inputs, and provide short, low-impedance supply connections. Decoupling capacitors should be placed at the relevant supply pins. The exposed thermal pad and the ground pins should be connected to an uninterrupted ground plane according to the manufacturer land-pattern guidance. This page consolidates verified manufacturer and distributor information, documents unavailable specifications rather than estimating them, distinguishes the confirmed same-package family candidate from unsupported replacements, and provides application and layout guidance beyond a raw catalog listing.
TPS65191RHBR - 7-Channel TFT-LCD Scan Driver | Texas Instruments
Texas Instruments TPS65191RHBR is a seven-channel high-voltage scan driver for TFT-LCD panels, packaged in a 32-pin VQFN surface-mount package. The verified product information identifies a high output-voltage level of 35 V, a low output-voltage level down to -28 V, logic-level inputs, triple high-voltage scan-driver capability, scan-driver output charge sharing, and an exposed pad for improved thermal performance. The distributor listing describes the device as a video shifter IC for LCD displays and TFT-LCD panel scan driving. A high-voltage LCD scan driver is a specialized interface and display-driver IC that generates the gate and source drive signals required by TFT-LCD panels. It belongs to the video-processing and display-interface hierarchy: TFT-LCD scan driver, level shifter, video processing IC, display driver, and interface semiconductor. By combining high-level scan outputs with low-level output capability, the TPS65191RHBR supports TFT-LCD panels that require multiple high-voltage signal channels driven from logic-level control circuitry. The primary verified features are the seven-channel architecture, 35 V high output level, -28 V low output level, logic-level inputs, and output charge sharing. Charge sharing can reduce the switching burden associated with panel drive signals by transferring charge between outputs, although exact timing, output-impedance, channel-mapping, and timing-window limits must be confirmed in the manufacturer datasheet before layout and firmware are finalized. Technically, this device sits between an LCD controller and the TFT-LCD gate or scan lines. Its logic-level inputs allow a digital display controller or FPGA to command the required output states, while the internal high-voltage output stage provides the voltage swing needed by the panel. The 32-VQFN package also has an exposed thermal pad, giving the PCB designer a direct heat-spreading path; exact pad dimensions, pin functions, thermal resistance, and recommended land pattern remain to be verified from the official documentation. Typical uses include TFT-LCD monitor and panel electronics, small-format display systems, industrial HMI panels, automotive display modules, portable instruments, and embedded control systems with dedicated LCD scan electronics. The TPS65191RHBR is particularly relevant where a board requires a dedicated seven-channel high-voltage scan driver rather than relying on a controller with integrated high-voltage panel outputs. The main design consideration is that panel timing and voltage compatibility are not determined by the driver description alone. Designers must match the panel's required channel count, gate voltage range, logic thresholds, timing sequence, and charge-sharing behavior. Input and output routing should be kept short, the exposed pad must be connected to the recommended ground and thermal area, and datasheet limits must be checked against worst-case supply and temperature conditions. This page combines verified distributor specifications, family-level comparison information, pinout availability constraints, and practical TFT-LCD design guidance. It distinguishes confirmed parameters from information that must still be obtained from the manufacturer datasheet, helping engineers evaluate this scan driver without treating unspecified electrical details as guaranteed.
TPS65192RHDR - 9-Channel LCD Level Shifter | Texas Instruments
The Texas Instruments TPS65192RHDR is a 9-channel level-shifter integrated circuit for LCD displays, with gate voltage shaping and discharge functions in a 28-pin VQFN 5 x 5 mm package. It operates across a -40°C to +85°C temperature range. The device converts logic-level signals from a timing controller into the high-level gate-drive signals required by an LCD panel. Channels 1 through 7 are powered from VGH1 and VGL, while the remaining two channels use a separately identified supply arrangement in the product documentation. An LCD level shifter is an interface IC that translates voltage-domain signals between a display timing controller and source and gate driver circuits. Within the broader semiconductor hierarchy, it belongs to the voltage-level translation and display-interface ecosystem rather than the power-management regulator or processor categories. Its purpose is to preserve signal timing and establish the voltage swing required by display electrodes while limiting electrical stress on the controller. The TPS65192 provides nine independent level-shifting channels, gate voltage shaping, and discharge functions. These features support LCD panels used in televisions and monitors. The 28-pin VQFN package measures 5 x 5 mm, allowing a compact display-interface implementation while exposing separate display-signal, supply, ground, and control connections. The stated -40°C to +85°C range supports use across industrial and commercial temperature environments. Architecturally, the device is divided into two channel groups to support the timing relationships of an LCD panel. The first seven channels use the VGH1 and VGL supply domain, as identified by Texas Instruments. The other two channels form the second group. Gate voltage shaping and active discharge functions help the display interface maintain defined output states during signal transitions and panel-specific drive sequences. Typical applications include LCD television panels, computer monitors, timing-controller interfaces, large-format displays, and other TFT-LCD systems in which source or gate lines must be translated between logic and panel voltage domains. The device is particularly relevant when the timing controller cannot directly drive the voltage levels required by the LCD panel. Designers should treat the LCD panel requirements as the controlling specification. Verify VGH1, VGL, the second channel-group supply, signal timing, and output levels against the manufacturer datasheet. Place bypass capacitors close to the relevant supply pins and route high-voltage display-drive traces to minimize coupling into adjacent logic channels. The 5 x 5 mm VQFN footprint also requires thermal-aware layout and exposed-pad soldering verification. This page combines the verified Texas Instruments product description, package and temperature information, distributor availability references, honest pricing status, and a constrained drop-in comparison. It also identifies the electrical and pin-level data that must be confirmed in the manufacturer datasheet before layout or production release.
TPS65197BRUYR - 8-Channel LCD Level Shifter | Texas Instruments
Texas Instruments TPS65197BRUYR is an 8-channel LCD level-shifter IC with no, 2-channel, or 3-channel charge-sharing support and panel discharge to VGH during shutdown, packaged in a 28-pin WQFN (RUY) package. It is designed to manage the high-voltage and low-voltage signaling requirements encountered in LCD-panel gate-drive systems while reducing the number of discrete switching and level-translation functions on the board. An LCD level shifter is a specialized interface IC that translates gate-driver signals to the voltage domain required by an LCD panel. In the broader electronics hierarchy, this device is a display interface and voltage-level translator within interface ICs and semiconductor power-management-adjacent signal conditioning. The TPS65197 combines eight signal channels, configurable charge sharing, and shutdown panel discharge to support TFT-LCD panel timing and gate-drive architectures. The verified feature set centers on 8 independently addressed level-shifter channels, support for no, 2-channel, and 3-channel charge-sharing modes, and discharge of the panel to VGH when the device enters shutdown. These functions address the practical need to control gate-line transitions, reduce transition-load demand, and establish a defined off state for TFT-LCD panels. The 28-pin WQFN (RUY) package also supports compact display-controller designs where connector count and routing area are constrained. The RUY package is a 4 mm by 4 mm WQFN outline with 28 pins and a thermal pad, combining a small footprint with direct PCB heat-spreading capability. Its exposed pad provides a thermal path to the board copper rather than relying only on package leads. Although this is principally a signal-interface device rather than a power semiconductor, the exposed pad must still be connected according to the manufacturer land pattern and thermal guidance to preserve electrical performance, assembly yield, and temperature reliability. TPS65197BRUYR is appropriate for TFT-LCD monitor panels, industrial HMIs, small-format embedded displays, test equipment, and other systems requiring coordinated level translation, charge sharing, and controlled panel shutdown. Designers should match the panel's gate-line count, allowable charge-sharing mode, VGH operating behavior, signal timing, and shutdown requirements before finalizing a system design. The use of supported charge-sharing modes can lower effective switching load, while panel discharge provides a defined shutdown sequence. PCB layout should keep the level-shifter outputs and VGH-related connections short, preserve the manufacturer's recommended copper and thermal-pad geometry, and maintain clean return paths beneath the device. Designers must also validate output timing against the target panel because no, 2-channel, and 3-channel operation are not interchangeable for every controller. Power sequencing should be coordinated with the display controller so VGH is not removed before the required panel-discharge interval has completed. This page consolidates the verified TI product information, distributor availability, package details, pricing snapshot, selection guidance, and design considerations for TPS65197BRUYR. It also separates confirmed technical facts from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate panel compatibility without relying on assumptions.
TPS65197BRUYT - 8-Channel LCD Level Shifter | Texas Instruments
The Texas Instruments TPS65197BRUYT is an eight-channel level-shifter IC for LCD display applications, supplied in a 28-pin WQFN (RUY) package measuring 4 mm by 4 mm. It converts timing-controller logic-level signals into the higher gate-in-panel voltage levels required by LCD panels. The device supports two-channel and three-channel charge sharing, panel discharge to VGH during shutdown, and operation from a 16.5 V to 45 V supply range. Its specified operating temperature range is -40 °C to 85 °C. An LCD level shifter is a voltage-interface IC used between a display timing controller and the high-voltage gate-driver inputs of an LCD panel. Within the signal-chain hierarchy, it belongs to interface ICs and video ICs rather than a display driver or low-voltage digital logic device. Its principal purpose is to translate low-voltage timing signals while coordinating charge sharing and panel discharge, helping the display system reach a defined state during power transitions. The TPS65197 provides eight level-shifting channels together with clock outputs that support normal operation, two-channel charge sharing, and three-channel charge sharing. The manufacturer describes it as an eight-channel device intended for notebook, monitor, and television LCD panels. Charge-sharing support reduces the number of high-voltage gate-driver components required in suitable panel architectures, while the panel-discharge function provides a controlled path to VGH during shutdown. The 16.5 V minimum and 45 V maximum supply specification places the device in the high-voltage interface category used by LCD gate-driver systems. The exact channel-level voltage ranges, output-current limits, timing values, and enable or mode details were not present in the supplied verified excerpts and therefore must be checked against the complete manufacturer datasheet before layout or design release. Typical uses include notebook LCD panels, desktop monitors, television panels, and other display systems that translate timing-controller outputs into GIP gate-drive signals. Designers should pay particular attention to charge-sharing mode selection, shutdown sequencing, VGH discharge behavior, exposed-pad thermal management, and the recommended input and output timing layout. The 28-pin 4 mm by 4 mm WQFN package supports compact display-controller boards, but its fine pitch and exposed pad require disciplined PCB layout. Confirm the exact RUY land pattern, thermal-pad connection, voltage rails, and timing constraints using the current TI datasheet and application information before production. This page consolidates verified manufacturer and distributor information with package details, procurement data, display-use guidance, and explicit identification of specifications that still require confirmation. It distinguishes verified facts from missing technical parameters so engineers can assess suitability without relying on unverified assumptions.
TRS3232EIRGT - Dual RS-232 Transceiver, ±15kV ESD | TI
The Texas Instruments TRS3232EIRGT is a 3V to 5.5V dual-channel RS-232 line driver and receiver (transceiver) with ±15kV IEC ESD protection on the serial-port pins, delivering 250 kbps data rates in a compact 16-pin VQFN (RGT) 3x3 mm package. An RS-232 line driver/receiver is an interface IC that converts logic-level UART signals (TTL/CMOS, typically 0V to 3.3V or 5V) into the voltage-swing-compliant RS-232 levels required by serial-port connectors, and vice versa. It sits within the interface IC hierarchy of transceivers, alongside CAN, RS-485, and LVDS transceivers, and forms the electrical bridge between an asynchronous communication controller and the physical serial connector. Key features include two drivers and two receivers for full-duplex communication, a dual charge-pump circuit that generates RS-232 compliant voltage swings from a single 3V to 5.5V supply with only four small 0.1uF external capacitors, ±15kV IEC ESD protection pin to pin (including GND), and conformance to TIA/EIA-232-F. The 250 kbps data rate comfortably covers standard UART baud rates up to 250 kbaud. Technically, the device integrates an efficient regulated charge-pump inverter and doubler, so the driver outputs swing to the RS-232 defined levels even at a 3.3V supply. Receiver inputs tolerate up to ±30V, providing robustness against fault conditions. ESD structures rated to ±15kV (HBM and IEC air-gap) protect bus pins against electrostatic discharge events in field environments. Typical applications include industrial PLC and factory-automation serial links, point-of-sale terminals and barcode scanners, and legacy/debug UART ports on networking and embedded processor boards. The small VQFN-16 footprint suits space-constrained designs where an SOIC-16 is too large. Design consideration: ensure the four charge-pump flying capacitors and both supply bypass capacitors (0.1uF) are placed as close to the pins as possible; exceeding the 5.5V supply or omitting capacitors degrades signal swing and ESD robustness.

TS3USB221AQRSERQ1 - USB 2.0 1:2 Mux/Demux Switch | Texas Instruments
The Texas Instruments TS3USB221AQRSERQ1 is an ESD-protected, high-speed USB 2.0 (480-Mbps) 1:2 multiplexer/demultiplexer analog switch in a 10-pin UQFN (2.0 mm x 1.5 mm) package. It operates from a 2.3 V to 3.6 V supply, accepts I/O signals up to 5.5 V, and delivers a typical 1 GHz (900 MHz for the A-Q1 automotive grade) signal bandwidth, making it purpose-built for routing high-speed USB 2.0 differential pairs in space-constrained systems. A USB switch, also called a USB mux or DPDT analog switch, is a special-purpose analog switch IC that routes differential D+ and D- signal pairs from one USB host or controller to one of multiple downstream ports. In the system hierarchy, it sits between the USB PHY/controller and the USB connectors, complementing power management and ESD protection ICs in the connectivity signal chain. Such switches are essential when a hub or application processor has limited USB I/O ports that must be shared among several connectors. Key features of the TS3USB221AQRSERQ1 include an on-resistance of 6 ohm maximum with a typical delta rON of 0.2 ohm, low ON-state capacitance of 6 pF maximum (CIO), and 1.8 V-compatible control-pin inputs that simplify interfacing with low-voltage GPIO. When the OE pin disables the device, it enters a low-power mode drawing only 1 uA, and total power consumption is 30 uA maximum, which is critical for battery-powered designs. The integrated ESD protection is rated above 2000 V per the Human-Body Model (HBM), reducing the need for external transient-suppression diodes on the USB lines. The wide 1 GHz-class bandwidth allows USB 2.0 signals to pass with minimum edge and phase distortion, preserving eye-diagram margin at 480 Mbps. As an AEC-Q100 qualified device (TS3USB221A-Q1 family), it is validated for automotive ambient temperature ranges and supports automotive USB hubs and charging ports. Typical applications include automotive USB hubs and infotainment ports, cell phones and handsets, digital cameras, and notebooks where a hub or controller has limited USB I/Os that must be multiplexed between connectors. Design consideration: keep the switch close to the USB connector, match the differential pair layout through the device, and verify that the select (S) and enable (OE) logic levels are compatible with your controller GPIO; unused channel stubs should be minimized to preserve signal integrity.

TS5A3159DBVR - 1.1Ohm SPDT Analog Switch SOT-23-6 | Texas Instruments
The Texas Instruments TS5A3159DBVR is a single-pole double-throw (SPDT) analog switch designed to operate from 1.65 V to 5.5 V. It features a low ON-state resistance of 1.1 ohm typical (2.5 ohm maximum) with excellent ON-state resistance matching, and a break-before-make switching scheme that prevents signal distortion during channel transfer. The device comes in a 6-pin SOT-23 (DBV) package for space-constrained designs. An analog switch is a semiconductor device that selectively connects or disconnects an analog signal path under digital control, acting as a voltage-controlled relay. Analog switches are fundamental building blocks for signal routing, multiplexing, and sample-and-hold circuits within the broader signal conditioning and interface IC family. Key features include a wide 1.65 V to 5.5 V supply range supporting 1.8 V, 2.5 V, 3.3 V, and 5 V rails; fast switching times of approximately 70 ns (tON) and 40 ns (tOFF); and excellent total harmonic distortion (THD) performance. The select (IN) pin tolerates voltages up to 7 V, allowing voltages above VCC without damage. The device is also a drop-in replacement for the onsemi NC7SB3157, easing second-sourcing. The TS5A3159 uses a CMOS transmission gate architecture providing bidirectional signal flow and low leakage. ON-resistance is flat across the signal range, minimizing signal distortion in precision audio and sensor paths. Operation is specified from -40C to +85C for industrial and consumer environments. Typical applications include audio signal routing, portable battery-powered equipment, data acquisition multiplexing, and sensor front-end switching, where low ON-resistance preserves signal fidelity. When designing with this device, keep the IN pin below 7 V, decouple VCC with a 100 nF ceramic capacitor close to the pin, and account for ON-resistance variation over supply voltage and temperature when calculating insertion loss.
TUSB1046-DCI - 10Gbps USB Type-C DP Alt Mode Redriver | TI
The Texas Instruments TUSB1046-DCI is a VESA USB Type-C Alt Mode linear redriver crosspoint switch supporting USB 3.1 data rates up to 10 Gbps and DisplayPort 1.4 up to 8.1 Gbps for a downstream facing port (host), housed in a 40-pin WQFN (6x4 mm) package and operating from a single 3.3 V supply. A redriver is a signal-conditioning integrated circuit that compensates for inter-symbol interference (ISI) by amplifying and equalizing high-speed serial data without retiming it. In the power-management and signal-chain hierarchy, a linear redriver sits between a USB/DisplayPort source PHY and the USB Type-C connector, restoring signal amplitude lost across PCB traces and cables. Unlike retimers, linear redrivers preserve the original signal waveform shape, which makes them protocol-agnostic and simple to design in. Key features include support for USB 3.1 Gen 2 at 10 Gbps, DisplayPort 1.4 at 8.1 Gbps per lane, and several selectable levels of receive linear equalization that compensate for cable and board trace loss. The crosspoint switching architecture enables the VESA DisplayPort Alt Mode on USB Type-C Standard Version 1.1 configurations C, D, E, and F, allowing a single USB Type-C port to carry both USB 3.x data and DP video over the same four super-speed lanes. The linear (protocol-agnostic) architecture means the device can also support other USB Type-C Alt Modes beyond DisplayPort. Because equalization is linear and analog, no protocol handshake or configuration firmware is required for the high-speed path; control comes from straightforward GPIO/strap settings such as the channel and mode selection pins. Typical applications include dock hosts, notebook and tablet USB Type-C ports, motherboards with USB Type-C DisplayPort Alt Mode output, and industrial displays where a host must deliver both 10 Gbps USB 3.1 data and 4K DisplayPort video through one reversible connector. When designing with this device, budget trace loss carefully: the receive linear equalization levels must be chosen to match the total channel loss at 10 Gbps, and the 40-WQFN thermal pad should be well-grounded for signal integrity.

Key features include compliance with the USB 2.0 specification at full-speed (12 Mbps), up to three programmable downstream ports, fully-compliant integrated transceivers on all upstream and downstream ports, and an optional serial EEPROM interface for storing vendor-specific configuration data such as VID/PID. Architecturally, the TUSB2036 is implemented as a 3.3V CMOS digital state machine (ASIC) rather than a microcontroller, which means no firmware development, programming, or flash memory is required - the device is fully functional as soldered. A dedicated DP0PUR pin (pull-up resistor disable) simplifies implementation of onboard bus-power/self-power dynamic-switching circuitry, reducing external BOM cost in bus-powered designs. Typical applications include standalone USB hubs, monitors and docking stations with USB ports, printers and multifunction peripherals, set-top boxes, and industrial equipment requiring multiple USB device ports from a single host connection. A key design consideration is power configuration: in bus-powered mode all downstream ports must draw within the USB budget of 500 mA total, whereas self-powered designs use the DP0PUR-based switching scheme and require proper VBUS sensing on downstream ports. The optional serial EEPROM allows custom VID/PID programming without firmware.

The Texas Instruments TUSB2E22 is a USB-compliant eUSB2-to-USB 2.0 dual repeater (redriver) that bridges low-voltage eUSB2 interfaces on modern processors to standard USB 2.0 ports. It supports low-speed (LS), full-speed (FS), and high-speed (HS) signaling at up to 480 Mbps and is available in a 25-pin DSBGA (2x2 mm) package, with a 20-pin VQFN-FCRLF (3.5x3.5 mm) option in the family (TUSB2E22RZA). An eUSB2 repeater is a signal conditioning IC in the USB interface IC (redriver/repeater) family that converts between the 1.2 V single-ended eUSB2 signaling used by advanced low-voltage SoCs and standard 3.3 V-signaling USB 2.0 ports. It sits in the signal chain between the SoC eUSB2 PHY (eDSPr or eUSPr) and the external USB connector, regenerating signals to maintain USB 2.0 compliance. This device category is a critical enabler as process nodes shrink and I/O voltages fall below legacy USB levels. Key features include compliance to USB 2.0 and eUSB2 (rev 1.1), support for LS/FS/HS signaling, a dual repeater with a 2:2 crossbar mux, and host-and-device mode (DRD) support, allowing each repeater to be independently configured. Four eUSB2 compensation settings via the EQ0 and EQ1 pins let designers optimize output compensation for different channel-loss profiles, trace lengths, and connector losses. Architecturally, the TUSB2E22 retimes and re-drives USB signals, improving signal integrity over long traces and through connectors. The 2:2 crossbar mux supports flexible routing, including USB Type-C receptacle flipping where the D+/D- pair swaps between A6/A7 and B6/B7 positions. Power is supplied from VDD3V3 and VDD1V8 rails with no power-up sequence requirement between them; RESETB (active low) can also act as a power-down pin. Typical applications include USB Type-C ports on laptops and desktops, docking stations, USB hubs, and embedded systems whose SoCs expose only eUSB2. It is especially valuable where processor I/O voltage is too low for direct USB 2.0 signaling. Design consideration: configure EQ0/EQ1 per your PCB trace length and connector loss, decouple both supply rails well, and ensure VDD3V3/VDD1V8 ramp within 2 ms per the datasheet power-up recommendation.

The Texas Instruments TVP5146M2PFPR is a high-quality 10-bit single-chip digital video decoder that digitizes and decodes NTSC/PAL/SECAM composite and S-Video into digital component YCbCr, housed in an 80-pin HTQFP (PFP) package measuring 12x12 mm with an operating temperature range of 0 to 70 C. A digital video decoder is an analog front-end (AFE) IC that converts baseband analog video signals into digital component video suitable for processing by SoCs, DSPs, and FPGAs. Within the signal-chain hierarchy, it sits below video ADCs in abstraction: it integrates multiple high-speed ADCs (four 11-bit converters in this family), clock generation, synchronization separation, and color-space conversion on one die, making it a complete analog-video-to-digital-bridging solution for embedded video systems. Key features include 4x10-bit digital video output, A/D conversion of component RGB and YPbPr signals, an integrated 5-line adaptive comb filter that suppresses cross-luminance and cross-color artifacts in composite decoding, and Macrovision detection for copy-protection compliance. SCART support enables European consumer platform designs, and automatic standard detection of NTSC, PAL, and SECAM simplifies software bring-up. Architecturally, the TVP5146M2 digitizes the selected analog input through its embedded 11-bit ADC stage, applies analog clamping and gain control, then performs digital multi-standard decoding with the 5-line comb filter. YCbCr output is delivered over a standard parallel digital video port that interfaces directly to common video processors and display controllers. Linear-phase horizontal and vertical scaling-free output timing keeps downstream pipeline design straightforward. Typical applications include CCTV and DVR front ends, LCD monitors and TVs, video capture cards, set-top boxes, and industrial machine-vision equipment that must accept legacy composite, S-Video, YPbPr, or RGB sources. Design consideration: place a low-jitter crystal or clock source per the manufacturer datasheet layout guidance and keep analog inputs routed over a solid ground plane, since decoder SNR depends strongly on input clock jitter and analog layout quality.

A video decoder is a mixed-signal interface IC that sits at the front end of a video capture system, digitizing analog composite (CVBS) or S-Video signals so that a host processor, DSP, or video encoder can process them. Within the signal-chain hierarchy, it belongs to the video decoder family of interface ICs, bridging the analog broadcast world and the digital video processing domain. Key features include programmable output formats - 8-bit 4:2:2 with embedded syncs (ITU-R BT.656) or 8-bit 4:2:2 with discrete syncs - Macrovision copy protection detection, and complementary four-line adaptive comb filtering for both luminance and chrominance paths to reduce cross-luminance and cross-chrominance artifacts. A chrominance trap filter is also available as an alternative to comb filtering. The optimized architecture achieves ultralow power consumption, making the device especially suitable for battery-powered systems. A Genlock/real-time control (RTC) output is generated for synchronizing downstream video encoders, which simplifies the design of capture-and-display pipelines. Analog supply operates from 1.65V to 1.95V, and an I2C serial interface programs all decoder functions including input selection, contrast, brightness, saturation, and hue. Typical applications include cell phones and PDAs with video-in capability, portable media players and recorders, security/surveillance capture front ends, and set-top-box analog input ports. The 5x5 mm TQFP footprint suits space-constrained portable designs. Design consideration: the ultralow-power supply rails are tight (1.65V-1.95V analog core); plan a clean 1.8V LDO rail and follow the datasheet decoupling recommendations to preserve decoder signal-to-noise performance on the analog inputs.

TXB0104QRUTRQ1 - 4-Bit Auto-Direction Level Translator | TI
The Texas Instruments TXB0104QRUTRQ1 is an automotive-qualified 4-bit bidirectional voltage-level translator with automatic direction sensing, delivered in a compact 12-pin UQFN (RUT) package measuring 1.7 mm x 2.0 mm. It translates between a 1.2 V to 3.6 V A-port supply and a 1.65 V to 5.5 V B-port supply (VCCA <= VCCB), supporting data rates up to 100 Mbps. A voltage-level translator is a logic device that interfaces digital circuits operating at different supply voltages on the same PCB, such as a 1.8 V microcontroller talking to a 3.3 V or 5 V peripheral. translators sit within the broader logic IC hierarchy as members of the voltage-translation and signal-conditioning family used in mixed-voltage embedded systems. Key features include AEC-Q100 Grade 1 qualification (-40C to +125C ambient), +/-15kV IEC ESD protection on the I/O pins, and automatic direction sensing that eliminates direction-control pins or firmware overhead. The TXB family push-pull architecture uses internal one-shot edge accelerators, giving rise and fall symmetry suited to push-pull CMOS outputs. The 12-UQFN package enables very dense layouts in space-constrained automotive modules. Typical applications include automotive body electronics and lighting, infotainment and cluster SPI/I2C-adjacent push-pull signaling, sensor interface level shifting, and general-purpose MCU-to-peripheral level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V domains. The wide 1.2 V low-side support makes it suitable for next-generation low-voltage processors. Design note: this device is intended for push-pull CMOS signals; for open-drain buses such as I2C, choose the TXS family instead. Do not add external pull-up or pull-down resistors on TXB I/O lines, as they can defeat the automatic direction sensing.
