TVP5158IPNPR

TVP5158IPNPR - 4Ch NTSC/PAL Video Decoder, 128-HTQFP | Texas Instruments

The Texas Instruments TVP5158IPNPR is a four-channel high-quality NTSC/PAL video decoder that digitizes and decodes all popular base-band analog video formats into digital video output. Each of the four channels integrates a 10-bit 27-MSPS analog-to-digital converter (ADC) preceded by an analog input conditioning circuit that clamps the input to a reference and applies anti-alias filtering. The device is offered in a 128-pin HTQFP (PNP) package measuring 14x14 mm with an exposed thermal pad, targeting multi-channel security and machine-vision applications. A video decoder is a mixed-signal integrated circuit that converts analog composite video signals (such as those from CCTV cameras or legacy broadcast outputs) into a digital component video stream for downstream processing by a host processor, SoC, or DSP. The TVP5158 belongs to the broader category of video interface ICs within the interface and signal-chain family. It supports NTSC (J, M, 4.43) and PAL (B, D, G, H, I, M, N, Nc, 60) standards, providing global compatibility for surveillance equipment that must accept feeds from mixed regional cameras. Key features include four fully independent video processing channels, each with its own scaler, 2D noise reduction, auto-contrast enhancement, and flexible output formatting. Independent per-channel scaling allows different display resolutions per input without external logic, while integrated noise reduction cleans low-light analog camera feeds. An I²C control interface manages all programming. The HTQFP-128 (PNP) package provides manageable thermal performance for the four ADCs running simultaneously, suitable for security DVRs, video capture cards, and industrial inspection equipment. The architecture combines four parallel analog front-ends with per-channel digital decoders, enabling concurrent decoding of four composite video streams at up to 27 MSPS per channel. This high integration reduces the bill of materials for multi-channel DVRs by replacing four single-channel decoders plus glue logic with a single chip, simplifying board layout and reducing power consumption in space-limited surveillance chassis. Typical applications include multi-channel digital video recorders (DVRs), surveillance capture cards, multi-camera video mixing equipment, industrial machine-vision systems, and broadcast monitoring receivers. Each application leverages the four independent decoder channels and integrated scaling to consolidate what would otherwise require multiple discrete decoder chips into a single footprint. Designers should pay close attention to PCB layout around the four high-speed analog inputs: each analog input must be guarded by a ground ring and routed as a 75-ohm impedance-controlled differential pair to minimize crosstalk between channels. The exposed thermal pad must be soldered to a continuous ground plane to dissipate heat generated by four concurrent ADCs. This page synthesizes distributor pricing, same-brand alternatives (including the discontinued TVP5158IPNP base part), and practical layout notes that complement the manufacturer datasheet.

TVP5160PNP - NTSC/PAL/SECAM 10-Bit Video Decoder HTQFP-128 | TI
TVP5160PNP

TVP5160PNP - NTSC/PAL/SECAM 10-Bit Video Decoder HTQFP-128 | TI

The Texas Instruments TVP5160PNP is a high-quality digital video decoder that digitizes and decodes all popular baseband analog video formats into digital component video, integrating two 11-bit 60-MSPS analog-to-digital converters with analog preprocessors, fixed RGB-to-YUV color space conversion, and Macrovision detection. Housed in a 128-pin HTQFP (PNP) package measuring 14x14 mm, the device supports NTSC (J, M, 4.43), PAL (B, D, G, H, I, M, N, Nc, 60) and SECAM (B, D, G, K, K1, L) composite and S-Video inputs as well as component YPbPr and RGB (SCART) signals. A video decoder is an analog front-end IC that converts legacy analog video waveforms - originally designed for CRT displays - into digital YCbCr component streams for downstream processing by display controllers, scalar ASICs, video processors, or application processors. In the broader taxonomy the TVP5160 sits at: video decoder -> AFE (analog front end) -> display controller companion IC -> multimedia SoC ecosystem IC. Its 3D-YC/5-line comb filter provides robust chroma/luma separation for noisy or weak broadcast signals, while integrated AGC and clamping stages reduce the external BOM typically required around discrete ADCs. Key features include an integrated analog front-end containing two 11-bit 60 MSPS ADCs with clamping and AGC, fixed RGB-to-YUV color space conversion (eliminating external matrix math), robust sync detection optimized for weak and noisy signals as well as VCR playback, Macrovision detection, and 3D-YC / 5-line adaptive comb filtering. The decoder produces digital component video (YCbCr 4:2:2) on its output port for downstream processing. Operating voltage spans 3.0V to 3.6V (3.3V typical) with typical power dissipation of 904 mW. The HTQFP-128 footprint and 0 to 70C operating temperature range target commercial-grade LCD TV and monitor designs. Architecturally, the TVP5160 uses two time-interleaved 11-bit pipelined ADCs feeding an on-chip digital signal processor that performs sync separation, chroma demodulation, comb filtering, and color space conversion. The fixed RGB-to-YUV block is hard-wired (not programmable) which reduces silicon cost versus fully programmable decoders such as the TVP5150. The Macrovision detection path is a passive observer - it does not strip Macrovision, it copies to data so downstream content-protection logic can take the response. Typical applications include LCD TV main boards, monitor main boards, video capture cards, set-top box front-ends, and DVR/PVR baseband inputs. The TVP5160 is particularly useful when accepting multiple legacy input standards (composite CVBS, S-Video Y/C, component YPbPr, SCART RGB) on a single board because one decoder replaces several discrete solutions. The Macrovision detection path also enables DRM-aware DVR designs. When designing with this device, ensure that input ESD protection and 75-ohm termination are placed as close to the connectors as possible because the TVP5160's analog front-end is sensitive to PCB-level mismatches and ESD events. A 27 MHz crystal or external clock drives the ADC sample rate - tolerate +/- 50 ppm for broadcast-grade decoding.

TXB0104-Q1 - 4-Bit Auto-Direction Level Translator | TI
TXB0104-Q1

TXB0104-Q1 - 4-Bit Auto-Direction Level Translator | TI

The Texas Instruments TXB0104-Q1 is an automotive-grade 4-bit bidirectional voltage-level translator with automatic direction sensing and +/-15 kV ESD protection, available in a 14-pin TSSOP (PW) package. It translates between two independent supply rails: the A port tracks VCCA from 1.2 V to 3.6 V, while the B port tracks VCCB from 1.65 V to 5.5 V, enabling any-to-any translation between 1.2 V, 1.8 V, 2.5 V, 3.3 V and 5 V logic domains. A voltage-level translator is a logic-family device that allows integrated circuits operating at different supply voltages on the same PCB to exchange digital signals safely. Within the power-and-signal-management hierarchy, it sits alongside buffers and bus switches as a fundamental interface IC, preventing overvoltage damage and ensuring valid logic thresholds between low-voltage MCUs, FPGAs, and 5 V peripherals. Key features include auto-direction sensing, which eliminates the DIR control pins required by '245-style translators, a data rate of up to 100 Mbps, and VCC isolation: when either supply is at GND, all I/O enters Hi-Z. The AEC-Q100-qualified TXB0104-Q1 also carries +/-15 kV HBM ESD protection, exceeding the standard JESD ratings cited in the TI datasheet family. Architecturally, the TXB0104 uses a self-directed, edge-rate-driven one-shot scheme that detects the direction of each transition and briefly strengthens the opposite driver, allowing it to drive 4 channels in either direction without software intervention. The OE pin three-states all outputs for power sequencing and bus isolation. Typical applications include SPI and UART level conversion between 3.3 V MCUs and 5 V peripherals, GPIO expansion in automotive body and infotainment modules, and mixed-voltage FPGA I/O. Note that the push-pull architecture is not recommended for open-drain buses such as I2C or 1-Wire; use the TXS0104E-Q1 for those. Design consideration: keep unloaded outputs low-impedance driven or grounded, since the auto-direction circuitry can oscillate on lightly loaded or capacitively large nets; series resistors above 25 k-ohm are not supported. This page adds value beyond the TI datasheet by synthesizing distributor availability, drop-in alternatives (NXP NTS0304E, ADI ADG3304), and practical design notes for automotive level-shifter selection.

TXB0104D - 4-Bit Bidirectional Level Translator, 100Mbps | TI
TXB0104D

TXB0104D - 4-Bit Bidirectional Level Translator, 100Mbps | TI

The Texas Instruments TXB0104D is a 4-bit bidirectional voltage-level translator with automatic direction sensing, delivering up to 100 Mbps data rates in a 14-pin SOIC (D) package, with VCCA from 1.2V to 3.6V and VCCB from 1.65V to 5.5V plus +/-15 kV ESD protection. A voltage-level translator (also called a level shifter) is a logic IC that interfaces digital circuits operating at different supply voltages, allowing a 1.8V microcontroller to safely communicate with a 3.3V or 5V peripheral. Level translators sit within the broader logic IC family, alongside buffers, transceivers, and bus switches, and are a fundamental part of system power-management and signal-chain design wherever mixed-voltage domains coexist. Key features of the TXB0104D include fully automatic direction sensing that eliminates the direction-control pin required by conventional transceivers, universal translation among 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V nodes, and a 100 Mbps maximum data rate that supports fast embedded buses. An active-high OE input tri-states all eight I/Os when low, providing board-level power sequencing isolation. Architecturally, the TXB family uses two separate configurable power-supply rails: port A tracks VCCA and port B tracks VCCB. Internal one-shot circuits sense edges and briefly drive stronger pull-up/pull-down transistors, while a 4 kOhm series switch holds the level in static conditions. This push-pull CMOS design requires neither pull-up resistors nor direction control, but it does mean the TXB0104 is suited to push-pull CMOS outputs only, not open-drain buses unless replaced by the TXS family. Typical applications include MCU-to-peripheral interfacing across mixed voltage domains, SPI and UART signal translation, and general-purpose 1.2V-to-5V logic bridging in industrial and consumer systems. The -40C to +85C operating range covers most commercial and industrial environments. Design consideration: keep VCCA lower than or equal to VCCB, and remember the weak static drive (about 4 kOhm) cannot handle heavy loads, long wires, or pull-up resistors below about 50 kOhm.

TXB0104RUTR

TXB0104RUTR - 4-Bit Bidirectional Level Shifter | Texas Instruments

The Texas Instruments TXB0104RUTR is a 4-bit bidirectional voltage-level translator with automatic direction sensing and ±15-kV ESD protection (Human Body Model), housed in a 12-pin UQFN (RUT) package measuring 1.7 mm x 2.0 mm. It translates signals between a low-voltage A port operating from 1.2 V to 3.6 V and a higher-voltage B port from 1.65 V to 5.5 V (VCCA <= VCCB), supporting data rates up to 100 Mbps. A voltage-level translator, also called a level shifter, is an integrated circuit in the logic-translation family that enables communication between digital devices operating at different supply voltages. In mixed-voltage systems, a 1.8 V or 3.3 V MCU may need to interface with 5 V peripherals; translators convert logic levels bidirectionally while protecting low-voltage silicon. The TXB0104 belongs to the auto-direction-sensing translator family, eliminating direction-control pins and simplifying both PCB design and firmware. Key features include per-channel automatic direction sensing, ±15-kV HBM ESD protection on all pins, tri-state outputs with an output-enable (OE) pin for bus isolation, and an operating temperature range of -40C to +85C. Low quiescent current and the tiny UQFN footprint suit space-constrained portable designs. Architecturally, the TXB0104 uses a one-shot edge accelerator that speeds rising and falling edges, enabling 100 Mbps operation with low static power. The A port tracks VCCA and the B port tracks VCCB. Partial power-down via OE and Ioff-style isolation make it suitable for hot-insertion environments. Typical applications include SPI, UART, and push-pull GPIO level shifting between MCUs, sensors, SIM card and SD card interfaces, and memory peripherals in mobile, industrial, and consumer products. The push-pull driver topology is not recommended for open-drain buses such as I2C or 1-Wire, as confirmed in TI E2E forum threads. Design tip: power VCCA before VCCB, place 0.1 uF bypass capacitors close to both supply pins, and use the OE pin for sequencing. For open-drain buses, consider TXS0104E instead.

TXB0104W-Q1 - 4-Bit Auto-Direction Level Translator | Texas Instruments
TXB0104W-Q1

TXB0104W-Q1 - 4-Bit Auto-Direction Level Translator | Texas Instruments

The Texas Instruments TXB0104W-Q1 is an automotive-grade 4-bit bidirectional voltage-level translator with automatic direction sensing, rated for data rates up to 100 Mbps and protected by +/-15 kV IEC ESD protection on the I/O pins, housed in a 12-pin UQFN (RUT) package. Qualified per AEC-Q100 for automotive applications, the W variant supports a VCCA supply range of 1.1 V to 3.6 V and a VCCB range up to 3.6 V, translating between logic families such as 1.2 V, 1.8 V, 2.5 V, and 3.3 V rails. A voltage-level translator is a member of the logic IC family (voltage-level translator -> logic IC -> integrated circuit) that allows two circuit domains operating at different supply voltages to exchange digital signals safely. On mixed-voltage PCBs - for example, a 1.8 V microcontroller talking to a 3.3 V sensor - the translator isolates the rails while preserving logic polarity and timing, preventing overvoltage damage and logic-level misreads. Key features of the TXB0104W-Q1 include automatic direction sensing that eliminates DIR control pins, push-pull topology optimization delivering 100 Mbps throughput, and a compact 12-pin UQFN footprint of approximately 2 mm x 2 mm that saves board area. The +/-15 kV ESD rating (IEC) on the I/O ports adds robustness in harsh automotive electrical environments. According to TI product data, the device uses two separate configurable power-supply rails; the A port tracks VCCA and the B port tracks VCCB. Architecturally, the TXB family uses a two-transistor output driver with an integrated one-shot edge-rate accelerator on each side, giving fast transition times for push-pull CMOS signals. This makes it well suited to SPI, UART, and general-purpose push-pull GPIO translation. Note that, as TI applications guidance states, the TXB architecture is not recommended for open-drain buses such as I2C or 1-Wire, where the internal drivers contend with external pull-ups. Typical applications include automotive body electronics and gateways translating between 1.8 V SoC GPIO and 3.3 V peripherals, infotainment and display module signal interfaces, and industrial control modules requiring AEC-Q100 qualified components. Design tip: keep VCCA ramps before or after VCCB within datasheet sequencing guidance, and place the two 0.1 uF decoupling capacitors directly at the VCCA and VCCB pins; the auto-direction sensing requires push-pull sources on both sides to function reliably.

TXB0104YZTR

TXB0104YZTR - 4-Bit Auto-Direction Level Translator | TI

The Texas Instruments TXB0104YZTR is a 4-bit bidirectional voltage-level translator with automatic direction sensing, supporting 1.2V to 3.6V on the A port and 1.65V to 5.5V on the B port at data rates up to 100 Mbps, housed in a 12-ball DSBGA (YZT) package measuring 1.9 mm x 1.4 mm with +/-15 kV ESD protection. A voltage-level translator is a logic-interface device that allows integrated circuits operating at different supply voltages - for example a 1.8V microcontroller and a 5V sensor - to exchange digital signals reliably. Within the power-management and interface hierarchy, level translators sit between logic families such as CMOS and TTL, complementing buffers, bus switches, and transceivers in the broader signal-chain category. Without translation, low-voltage logic can be damaged by higher-voltage inputs or fail to meet higher-voltage logic thresholds. Key features of the TXB0104 include its two separate configurable power-supply rails (VCCA tracks the A port, VCCB tracks the B port, with VCCA <= VCCB), auto-direction sensing that eliminates direction-control pins, a maximum propagation delay of 13.7 ns, and 4 kV (HBM) class robustness supplemented by +/-15 kV IEC ESD protection on the I/O lines. The TXB architecture uses a mixed-charge pump output driver that pushes data in either direction without OE-based handshaking. Technically, the device derives its drive from a 4 kOhm output stage optimized for lightly loaded, point-to-point CMOS links; it is not a bus-holder for heavily capacitive or high-fanout loads. The 0.5 mm ball pitch and wafer-scale DSBGA packaging minimize board area, making it attractive for dense portable designs. The output enable (OE) pin tri-states all channels for power-aware sequencing. Typical applications include translating I2C-adjacent push-pull buses, SPI and UART links between 1.8V MCUs and 3.3V or 5V peripherals, SD-card interfaces, and general-purpose GPIO bridging in industrial and consumer systems. A key design consideration: avoid capacitive loads above roughly 30 pF and pull-up/pull-down resistors below about 25 kOhm, because the auto-direction scheme relies on one side driving the line; contested drivers cause bus contention. This page synthesizes distributor pricing, verified specifications, and practical design guidance for the TXB0104YZTR beyond what any single datasheet page provides.

TXB0108PWR

TXB0108PWR - 8-Bit Bidirectional Level Shifter 100Mbps | TI

The Texas Instruments TXB0108PWR is an 8-bit bidirectional voltage-level translator with auto-direction sensing and +/-15-kV ESD protection, housed in a 20-pin TSSOP (PW) package. It translates signals between a 1.2V to 3.6V A port and a 1.65V to 5.5V B port (VCCA <= VCCB), with data rates up to 100 Mbps, making it ideal for mixed-voltage digital systems. A voltage-level translator is a logic IC that enables communication between devices operating at different supply voltages, such as a 1.8V microcontroller and a 3.3V or 5V peripheral. It sits in the hierarchy of logic ICs under level shifters (translators), which are essential in multi-voltage digital systems alongside buffers and bus transceivers. The TXB0108PWR uses auto-direction sensing, eliminating the need for a direction control pin and reducing firmware complexity. Key features include auto-direction sensing, +/-15-kV ESD protection (HBM), a 100 Mbps maximum data rate, and a VCC isolation feature: if either VCC input is at GND, all outputs enter the high-impedance state, enabling partial-power-down operation with Ioff support. The device operates from -40C to +85C. Technically, the TXB0108 uses a one-shot architecture that accelerates low-to-high transitions to achieve 100 Mbps. It is designed for push-pull (totem-pole) CMOS drivers only; for open-drain buses such as I2C, TI recommends the TXS0108E. Output drive is intentionally weak (internal 4 kOhm series resistors), so heavy capacitive loads above ~70 pF reduce achievable speed. Typical applications include 1.8V-to-3.3V microcontroller-to-sensor interfaces, SD card level shifting, UART/SPI signal translation, and FPGA configuration buses. The 100 Mbps capability suits high-speed SPI and UART links. Design tip: ensure VCCA <= VCCB, drive all eight channels push-pull, and place 0.1uF decoupling capacitors close to both VCCA and VCCB pins with short traces for signal integrity.

The Texas Instruments TXB0108QPWRQ1 is an automotive-qualified (AEC-Q100) 8-bit bidirectional voltage-level translator with auto-direction sensing and ±15kV ESD protection, packaged in a 20-pin TSSOP (PW). Port A supports 1.2V to 3.6V supplies while Port B supports 1.65V to 5.5V, enabling translation between any two logic rails in these ranges. A voltage-level translator (also called a logic level shifter) is an interface IC that enables digital devices operating on different supply rails - such as a 1.8V microcontroller and a 5V peripheral - to communicate reliably. Translators sit within the broader logic IC family, under interface and signal-conversion devices, and are essential wherever mixed-voltage systems coexist on one board. Key features include auto-direction sensing that eliminates the need for a direction-control pin, an output-enable (OE) input that places all I/O in Hi-Z when low, and ±15kV IEC ESD protection on I/O pins. The TXB0108-Q1 uses TI TXB-type push-pull architecture, delivering symmetric drive on both ports without external pull-up or pull-down resistors, and supports data rates up to 100 Mbps for 1.2V to 3.6V translation per the datasheet. The device operates from -40C to +125C (AEC-Q100 Grade 1), making it suitable for harsh automotive environments. Its TSSOP-20 package is standard, easy to assemble, and compatible with the commercial TXB0108PWR footprint for design reuse. Typical applications include automotive infotainment and cluster modules interfacing 3.3V MCUs with 5V sensors, mixed-voltage SPI/I2C-style GPIO expansion, industrial control modules, and portable mixed-signal systems bridging 1.8V and 5V rails. Design note: the TXB architecture has relatively weak output drive (not intended for bus-holding or heavy loads); avoid using it for I2C open-drain buses - the TXS family is a better fit. Pull OE low during power sequencing to prevent bus contention.

It operates with two separate power-supply rails, VCCA and VCCB, each configurable from 0.9V to 3.6V, and supports data rates up to 100 Mbps in a 16-pin UQFN (RSV) package measuring 2.6mm x 1.8mm, ideal for space-constrained designs. A voltage-level translator is a crucial component in modern electronics, allowing communication between ICs operating at different voltage levels. For example, a 1.8V microcontroller can interface with a 3.3V sensor or memory device without risking damage or logic errors. The TXB0304 belongs to the TXB family of auto-direction-sensing translators, part of TI's broader level-shifting portfolio that includes unidirectional and bidirectional solutions for various interface standards. Key features include a fully symmetric supply range (0.9V to 3.6V on both VCCA and VCCB), automatic direction sensing that detects data flow without external direction control, and a high data rate of 100 Mbps. The device also provides an isolation function: if either VCC input is at GND, all outputs are placed in a high-impedance state, preventing backflow current and protecting the system. Technically, the TXB0304 uses a one-shot circuit to accelerate rising edges, ensuring fast signal propagation even with capacitive loads. The architecture includes a pass-gate transistor with a pull-up resistor on each I/O pin, providing robust translation. The device is specified from -40C to +85C, is RoHS compliant and lead-free. Typical applications include SPI, I2C, UART, and GPIO interfacing between microcontrollers, sensors, memory, and peripherals at different voltage levels, particularly in IoT devices, portable electronics, and industrial control systems. Design tip: ensure both VCCA and VCCB are powered and place decoupling capacitors close to the power pins. Note that push-pull drivers are preferred; open-drain buses require external pull-ups sized carefully.

TXB0604 - 4-Bit Auto-Bidirectional Level Translator 345Mbps | TI
TXB0604

TXB0604 - 4-Bit Auto-Bidirectional Level Translator 345Mbps | TI

The Texas Instruments TXB0604 is a 4-bit non-inverting auto-bidirectional voltage level translator that uses two separate configurable power-supply rails: the A port tracks VCCA (0.9V to 2V) and the B port tracks VCCB (1.65V to 3.6V), with the constraint VCCA <= VCCB. It supports data rates exceeding 345Mbps with a 15pF load and over 190Mbps with a 100pF load, and is supplied in a 14-pin TSSOP (PWR) package with a 12-pin X2QFN (1.6x1.6mm) option (RWBR). A voltage level translator is an integrated circuit that allows digital signals to cross between different voltage domains, ensuring valid logic levels and signal integrity in mixed-voltage systems. Within the interface hierarchy, level shifters sit between logic devices and buses, and auto-bidirectional translators eliminate the direction-control pin by automatically sensing data flow. Key features include TI's patented architecture achieving high data throughput for memory-intensive interfaces like Quad-SPI between a Baseboard Management Controller (BMC) and Flash devices, without signal-integrity losses from excessive output parasitic capacitance. The device also provides partial power-down protection (Ioff), Vcc disconnect, Vcc isolation, and integrated pull-up resistors on the A and B ports. Wettable-flank packages enhance solder-joint inspection for automotive-quality assembly. Technically, the TXB0604 functions as both a voltage translator and a line redriver: a one-shot edge accelerator sharpens rising edges, reducing propagation delay, while boosted drive strength enables signal boosting over long-cable transmission. Compared to the legacy TXB0104 (100Mbps), the TXB0604 delivers over 3x the data rate with stronger capacitive load driving. Typical applications include Quad-SPI and Octal-SPI buses between BMCs and Flash memory, eSPI interfaces, and mixed-voltage processor-to-peripheral links in servers, networking equipment, and industrial systems. Design tip: always ensure VCCA <= VCCB, place decoupling capacitors close to both supply pins, and avoid floating unused inputs in partial power-down states. Pricing below is as of 2026-08-30.

TXE8124-Q1

TXE8124-Q1 - 24-Bit Automotive SPI I/O Expander | TI

The Texas Instruments TXE8124-Q1 is an automotive-grade 24-bit SPI bus I/O expander with interrupt output, reset input, and I/O configuration registers, operating from a 1.65V to 5.5V VCC supply and available in a VQFN-32 (RHB) package. An SPI I/O expander is a type of interface IC within the broader semiconductor hierarchy (interface IC -> I/O expander -> logic/integration device) that adds general-purpose parallel input/output pins to a microcontroller or processor using the four-wire Serial Peripheral Interface protocol. It belongs to the same product family as GPIO extenders and port expanders, and is the SPI counterpart to I2C expanders such as the PCX857x family, offering higher speed and deterministic timing. Key features include 24 configurable GPIO channels with individual I/O configuration registers, a dedicated interrupt output (INT) that flags input state changes to the host controller, and a reset input (RST) for rapid recovery of the register map to a known default state. The device supports both standard point-to-point SPI communication and daisy-chaining of multiple devices, allowing several expanders to share a single SPI chip-select in dense I/O designs. Performance scales with supply voltage: according to the Texas Instruments datasheet, the TXE8124-Q1 supports a 10MHz SPI clock when VCC is 3.3V to 5.5V and 5MHz when VCC is 1.65V to 5.5V. This voltage-flexible operation allows direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic domains without level translation in many systems. Typical applications include automotive body control modules, gateway ECUs, and infotainment boards that need additional GPIO for switches, push-buttons, sensors, LEDs, fans, and relay drivers when the host processor has exhausted its native GPIO. Daisy-chaining suits seat-control modules and door zones where dozens of switches must share one SPI port. When designing with this device, plan daisy-chain timing budgets around the 10MHz maximum clock and account for the added shift-register latency per cascaded device; also verify the interrupt output is polled or serviced before the register state can change again.

The Texas Instruments TXE8148DGGR is a 48-bit SPI bus I/O expander with interrupt output, reset input, and I/O configurable registers, delivering 48 general-purpose I/Os across six 8-bit ports with 10 MHz SPI operation from a 1.65 V to 5.5 V supply in a 56-pin TSSOP package. An I/O expander is a peripheral interface IC that increases the number of input/output pins available to a host microcontroller or processor without changing the host silicon. In the digital system hierarchy it sits between the host bus master (SPI in this case) and the GPIO load, functioning as a bridge in the broader family of interface ICs. I/O expanders such as the TXE8148 offload pin-count-constrained MCUs, allowing one SPI bus to control dozens of additional digital signals with only four host wires plus chip select. Key features include per-I/O programmable open-drain or push-pull outputs, programmable pullup and pulldown resistors, bus-hold latchable inputs, maskable interrupts with an interrupt status register, and a fail-safe operating mode. The device also supports daisy-chaining of multiple TXE8148 units on a single SPI bus, and documentation is available to aid functional safety system design. Technically, the TXE8148 maintains a 10 MHz SPI bus frequency across the entire 1.65 V to 5.5 V VCC range, which is significant for mixed-voltage designs where many expanders derate speed at low supply. The six-port, eight-I/O-per-port register map gives engineers byte-aligned access to all 48 channels, and the reset input provides deterministic recovery of all registers to a known default state after a fault or watchdog event. Typical applications include industrial control panels that need many switch inputs and relay outputs, functionally safe systems requiring documented failure modes, and server or networking backplanes where a processor must monitor dozens of card-present, fault, and status signals. Design consideration: plan your interrupt strategy early - the maskable interrupt and status register let the host poll a single register instead of 48 GPIOs, but interrupt masks must be configured after every reset since registers return to defaults.

TXG1010 - 1-Bit ±10V Ground-Level Translator | Texas Instruments
TXG1010

TXG1010 - 1-Bit ±10V Ground-Level Translator | Texas Instruments

The Texas Instruments TXG1010DSER is a 1-bit, fixed-direction, non-galvanic voltage and ground-level translator supporting logic-level shifting between 1.71V and 5.5V and ground-level shifting of up to ±10V, housed in a small 8-pin SOT-23 (DSE) surface-mount package. A level translator (also called a level shifter or voltage translator) is a logic IC that enables communication between digital circuits operating at different supply voltages, for example a 1.8V microcontroller driving a 5V peripheral. Within the signal-chain hierarchy, the TXG1010 belongs to the voltage-level-translation family of interface ICs. What distinguishes the TXG1010 family from traditional level translators is its ability to shift signals not only between different logic levels but also across different ground domains, solving the challenge of voltage translation between subsystems whose grounds differ by up to ±10V. Key features include a wide 1.71V to 5.5V logic-level translation range, ±10V ground-level shifting capability, a fixed-direction architecture that removes the need for a direction-control pin, and a single-channel (1-bit) topology that minimizes board area. The non-galvanic approach means there is no isolation barrier; the device tolerates ground potential differences rather than providing reinforced isolation, which is an important distinction from digital isolators. Technically, the device translates a logic input referenced to one ground domain into an output referenced to a second ground domain, while simultaneously performing standard low-voltage logic up- or down-translation. The fixed-direction design simplifies control logic and reduces pin count, making it suitable for one-way status, enable, and control signals. Typical applications include ground-offset compensation between a controller and a motor driver, level shifting in automotive and industrial subsystems where ground lift occurs under load, and interfacing between negative-rail or high-side circuitry and a low-voltage MCU. When designing with the TXG1010, remember that it is non-galvanic: sustained ground differences must remain within the ±10V rating, and it should not be used where safety isolation is required. Refer to the manufacturer datasheet for the exact truth table and supply sequencing requirements.

TXG1021-Q1 - ±10V 2-bit Ground-Level Translator | TI
TXG1021-Q1

TXG1021-Q1 - ±10V 2-bit Ground-Level Translator | TI

The Texas Instruments TXG1021-Q1 is an automotive-qualified 2-bit, fixed-direction, non-galvanic ground-level translator supporting DC ground shifts up to ±10V and logic-level shifting between 1.71V and 5.5V, with propagation delay under 5ns and data rates above 250Mbps in an 8-pin SOIC package. A ground-level translator is a specialized voltage translator that solves a problem conventional level shifters cannot: signals referenced to grounds that sit at different DC potentials. In a classic automotive or industrial system, heavy load currents lifted through shared harness returns create millivolt-to-volt offsets between a sensor ground and a controller ground. Standard level shifters interpret those offsets as logic errors, while a non-galvanic ground-level translator tolerates the DC offset directly on its inputs while still reproducing clean logic edges at the destination domain. Key features include AEC-Q100 qualification for automotive deployments, DC shift tolerance up to ±10V, AC noise rejection of 20VPP up to 45MHz, and common-mode transient immunity (CMTI) of 1kV/us. Channel-to-channel skew is below 0.20ns and propagation delay stays under 5ns, so the device does not become a timing bottleneck even in fast digital links. Quiescent power consumption is low at approximately 0.8mA per the manufacturer datasheet. Architecturally, the TXG102x family uses a non-galvanic coupling approach rather than isolation barriers, giving it near-zero added latency compared with digital isolators while still rejecting ground potential differences. This makes it attractive for bridging control grounds in battery-managed, motor-driven, or switched-load environments where return paths are far from ideal. Typical applications include automotive body-control and gateway modules, motor inverter gate-drive signaling across shifted grounds, industrial PLC I/O with grounded sensor offsets, and battery-management communication lines where cell-stacking creates ground potential differences. Design consideration: verify that expected DC ground offset stays within the ±10V rating under all load and fault conditions, and follow the datasheet layout guidance for the ground-shifted domain. This page adds value beyond the manufacturer datasheet by synthesizing drop-in alternatives, comparison tables, and practical design notes in one place.

TXG4021-Q1 - ±40V 2-bit Ground-Level Translator | TI
TXG4021-Q1

TXG4021-Q1 - ±40V 2-bit Ground-Level Translator | TI

The Texas Instruments TXG4021-Q1 is an automotive-grade, 2-bit, fixed-direction, non-galvanic ground-level translator supporting logic-level shifting between 1.71V and 5.5V and ground-level shifting up to ±40V, delivered in an 8-pin SOIC (D) package with a maximum data rate of 264 Mbps. A ground-level translator is a specialized type of voltage level shifter within the broader logic IC family. While standard level translators only shift logic thresholds between supply domains (for example 3.3V to 5V), a ground-level translator also bridges systems whose ground references differ by tens of volts - a common condition in automotive and industrial environments where load currents in shared returns lift local ground potentials. The TXG402x-Q1 family solves this without galvanic isolation, offering a lower-cost, smaller-footprint alternative to digital isolators where only ground-offset tolerance is needed. Key features include the ±40V ground-shift tolerance, the 1.71V to 5.5V logic-level range on both sides, a fixed (unidirectional) direction configuration with two channels in a 1/1 arrangement, and a 264 Mbps maximum data rate. The -Q1 variant is qualified for automotive applications per TI's automotive qualification flow, supporting AEC-oriented design flows. Architecturally, the device is non-galvanic: input and output stages share a common substrate reference topology that tolerates large ground differentials while translating logic swings, unlike optocoupler or transformer-based isolators. This yields lower propagation delay and lower cost than isolation approaches, with the trade-off that the ground offset is tolerated rather than fully isolated. Typical applications include automotive body electronics and lighting modules, motor-drive gate-drive interfaces where ground lift occurs, and industrial PLC I/O cards bridging a 1.71V-5.5V controller domain to a high-side domain with a shifted ground. Design consideration: because the part is unidirectional, confirm signal direction is fixed in your topology; it cannot be used for bidirectional buses such as I2C without external direction handling.

TXG4042-Q1 - Automotive ±40V 4-bit Ground-Level Translator | TI
TXG4042-Q1

TXG4042-Q1 - Automotive ±40V 4-bit Ground-Level Translator | TI

The Texas Instruments TXG4042-Q1 is an automotive-grade, ±40V, 4-bit fixed-direction ground-tolerant voltage level translator in a 2/2 push-pull configuration, housed in a 16-pin SSOP package. It supports DC ground shifts up to ±40V, AC noise rejection up to 130 VPP at 1 MHz, and a common-mode transient immunity (CMTI) of 1 kV/μs. The device delivers a maximum propagation delay of 8.5 ns, channel-to-channel skew of 2 ns, and supports data rates up to 100 Mbps. Low power consumption is 0.7 mA per channel at 1 Mbps with a 1.8 V supply, making it efficient for always-on automotive networks. The TXG4042-Q1 is specifically designed to interface low-voltage MCUs with high-voltage domains in systems where the grounds are not co-located, such as in EV traction inverters, motor drives, and industrial PLC I/O modules. A ground-level translator (also called a ground-level shifter) is a specialized class of voltage level translator that operates correctly even when the local ground reference of the input side differs substantially from the local ground reference of the output side. Unlike generic level shifters that only translate voltage thresholds, ground-level translators reject large common-mode DC offsets (typically ±25V to ±50V) between the two sides. This category of IC sits within the broader hierarchy of voltage translators -> interface ICs -> signal conditioning -> integrated circuits. They are essential in safety, motor-control, and renewable-energy systems where isolated high-side circuitry must communicate with low-voltage digital controllers over short, non-isolated links. Key features include robust ±40V DC ground-shift tolerance, high AC noise rejection of 130 VPP at 1 MHz, excellent 1 kV/μs CMTI for fast switching transients, push-pull output drivers with edge acceleration for clean edges at high data rates, and a wide 1.71 V to 5.5 V supply range on the low-voltage side. The fixed 2/2 direction (2 inputs / 2 outputs in one direction, 2 in the other) simplifies firmware and eliminates direction-control pins, reducing BOM cost and PCB area. AEC-Q100 qualification makes the TXG4042-Q1 suitable for automotive temperature grade 1 (-40 °C to +125 °C) operation. Architecturally, the TXG4042-Q1 uses TI's capacitorless, two-channel ground-shift topology with internal high-voltage blocking transistors on each channel. The high-voltage side tolerates continuous DC offsets via integrated clamping and ESD structures, while the input/output structures on the low-voltage side are optimized for sub-5 V CMOS logic levels. The device requires no external bootstrap capacitors, inductors, or programming resistors, simplifying PCB layout and reducing BOM count compared to digital isolator-based alternatives. Typical applications include EV traction inverter gate-driver communication, automotive HVAC and body controllers interfacing with high-side sensors, industrial PLC mixed-voltage I/O links, solar inverter string-monitoring interfaces, and battery-management system (BMS) communications across isolated high-voltage domains. It is also well-suited for medical imaging systems, white-goods motor drives, and any application requiring safe digital communication across non-isolated grounds with significant DC offset. When designing with the TXG4042-Q1, ensure the high-voltage side stays within ±40 V relative to the local ground. Place the VCC bypass capacitor as close as possible to the supply pin to maintain noise margins, and avoid long high-side traces to minimize parasitic coupling. For multi-channel applications, observe the 2 ns channel-to-channel skew budget to preserve signal alignment at the receiver.

TXG4122

TXG4122 - ±40V Bidirectional I2C Ground-Level Translator | TI

The Texas Instruments TXG4122 is a dual (2-bit) bidirectional, non-galvanic voltage and ground-level translator designed specifically for I2C buses, housed in an 8-pin SOIC (D) package. It tolerates ground potential differences of up to ±40V, supports two separately configurable power-supply rails, and passes I2C signals at data rates up to 2 Mbps. A ground-level translator is a type of logic-level shifter within the broader family of signal interface and level-translation ICs. Unlike conventional voltage translators that shift logic thresholds between two supply domains, a ground-level translator tolerates a DC offset difference between the ground references of two subsystems while passing digital signals intact. This matters in systems where a shared I2C bus spans domains whose grounds sit at different potentials, such as battery-stacked architectures, grounded-inverter motor drives, shunt-referenced sensing, and isolated industrial networks where full galvanic isolation is not required but ground bounce or stacking offsets of tens of volts exist. Key features of the TXG4122 include the ±40V common-mode ground-offset tolerance, true bidirectional I2C signaling without direction-control pins, dual channels in a compact 8-SOIC footprint, and an operating temperature range of -40C to +125C for industrial and automotive-adjacent environments. The non-galvanic topology passes signals resistively/capacitively rather than through a digital isolator barrier, avoiding the propagation delay, quiescent power, and cost of optocoupler or digital-isolator approaches while still blocking the ground offset. Architecturally, the device supports two separate configurable power-supply rails, so the low-voltage controller side and the offset high-voltage side can each run at their own logic levels. Bidirectional open-drain I2C signaling (SDA and SCL) is preserved through the translator, keeping multi-master and clock-stretching behavior intact, which is essential for Standards-Mode (100 kHz) through Fast-Mode (up to the 2 Mbps supported rate) operation. Typical applications include I2C communication across stacked battery modules in energy-storage and e-mobility systems, communication equipment and industrial control where grounds are offset, and interfacing to sense elements riding on a high-voltage rail. Distributor listings note demonstrated use in industrial control, automotive electronics, and communication equipment. Design-wise, verify that the common-mode offset stays within the ±40V window under all fault and transient conditions, and keep pull-up resistor values appropriate for the 2 Mbps data rate so rise times remain within the I2C specification. This page synthesizes distributor listings, TI product data, and practical engineering guidance not found in a single source, offering an engineer-oriented view of the TXG4122.

TXH0137D-Q1 - 7-Bit 30V Level Translator | Texas Instruments
TXH0137D-Q1

TXH0137D-Q1 - 7-Bit 30V Level Translator | Texas Instruments

The Texas Instruments TXH0137D-Q1 is an automotive-qualified 7-bit, single-supply, fixed-direction voltage-level translator with inverted open-drain outputs, housed in a 14-pin TSSOP (PW) package rated from -40C to +125C. A voltage-level translator is a type of logic IC that converts digital signals from one voltage domain to another, sitting within the broader hierarchy of logic ICs, interface ICs, and semiconductors. Level translators are essential whenever chips operating at different supply rails - for example a 3.3V microcontroller and a 12V industrial sensor - must exchange signals safely. Fixed-direction translators like this one assign a permanent direction to each channel, avoiding the overhead and ambiguity of direction-control pins. Key features include 7 translation channels in a single package, open-drain outputs that support voltages up to 30V, and output currents up to 100mA per channel. The inverted output polarity allows the device to double as a level-shifting buffer-inverter, and the open-drain structure lets designers pull outputs to any rail within the 30V rating. As a Q1 device, it carries TI's automotive qualification for -40C to +125C operation. On the technical side, because output currents of up to 100mA per channel are very high for a level translator, the outputs are more susceptible to large overshoot caused by reactive loads. To address this, the TXH0137D-Q1 integrates clamping overshoot-protection diodes on its outputs, improving robustness against inductive and capacitive ringing in automotive wiring environments. Additionally, the open-drain outputs can be tied (paralleling) together to achieve higher aggregate current capability, a flexibility not found in push-pull translators. Typical applications include automotive body electronics and gateways, level-shifting between low-voltage MCUs and high-voltage sensors or actuators, industrial PLC I/O modules, and driving relays, LEDs, or solenoids that require more than the few milliamps a standard logic gate can source. The 30V output rating and 100mA drive make it a direct fit for 12V and 24V automotive rail signaling. A key design consideration: with open-drain outputs, external pull-up resistors are required, and their value sets both the output high level and the rise time. Size pull-ups to balance current consumption against edge speed, and rely on the integrated clamp diodes for overshoot events rather than external TVS in most designs.

TXS0102-Q1 - 2-Bit Auto-Direction Level Translator | TI
TXS0102-Q1

TXS0102-Q1 - 2-Bit Auto-Direction Level Translator | TI

The Texas Instruments TXS0102-Q1 is an automotive-grade, 2-bit bidirectional voltage-level translator for open-drain and push-pull applications, offered in an 8-pin VSSOP (DCU) package. It supports data rates up to 24 Mbps and interfaces logic operating at different voltage levels without a direction-control pin. A voltage-level translator, or level shifter, is a logic IC that connects incompatible logic families or systems operating at different supply voltages, such as a 1.65V microcontroller communicating with a 3.3V or 5V peripheral. Within the signal-chain hierarchy, level translators sit between logic ICs and interface ICs, enabling safe chip-to-chip communication where voltage mismatch would otherwise damage a driver or fail to meet input thresholds. Key features include auto-direction sensing on both channels, A-port supply (VCCA) from 1.2V to 3.6V and B-port supply (VCCB) from 1.65V to 5.5V, an output-enable (OE) input referenced to VCCA that places all I/O in high impedance when low, and internal 10 kOhm pull-up resistors on the I/Os that make the device ideal for open-drain drivers such as I2C buses. The -Q1 suffix denotes AEC-Q100 qualification for automotive applications. Technically, the TXS0102 architecture uses two NMOS pass transistors with 10 kOhm pull-ups per I/O, allowing either port to drive the signal while the opposite side is pulled to its rail. This push-pull capability plus open-drain support distinguishes it from passive FET translators and fixed-direction buffers. Typical applications include I2C and SMBus level translation in automotive body electronics, UART and GPIO bridging in cluster and infotainment modules, and low-speed sensor interface translation between 1.8V MCUs and 3.3V peripherals. Design tip: tie OE to GND through a pull-down resistor to guarantee high impedance during power-up, and for push-pull drivers note that the internal 10 kOhm pull-ups limit edge rates at heavy capacitive loads.

TXS0102DCUR

TXS0102DCUR - 2-Bit Bidirectional Level Shifter | Texas Instruments

The Texas Instruments TXS0102DCUR is a 2-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It enables digital switching compatibility between mixed-voltage systems using two separate configurable power-supply rails: the A ports support 1.65V to 3.6V while tracking VCCA, and the B ports support 2.3V to 5.5V while tracking VCCB. The device comes in an 8-pin VSSOP (DCU) package and operates from -40C to +85C. A voltage-level translator, also called a level shifter, is an integrated circuit that allows communication between components operating at different voltage levels. In mixed-voltage systems combining 3.3V microcontrollers with 5V sensors, or 1.8V logic with 3.3V peripherals, level shifters ensure logic high and low signals are correctly interpreted across voltage domains. The TXS0102 belongs to the bidirectional translator class, which shifts signals in both directions without a direction-control signal, simplifying design and reducing pin count within the broader logic IC and voltage-translation hierarchy. Key features include auto-direction sensing with no direction pin required, maximum data rates of 24 Mbps for push-pull and 2 Mbps for open-drain applications, and support for I2C, SMBus, and UART interfaces. A one-shot accelerator architecture speeds up rising edges even with capacitive loads. The OE pin, when low, places outputs in a high-impedance state for power sequencing and bus isolation. Technically, the TXS0102 uses a pass-gate architecture with integrated pull-up resistors on both A and B ports. When a line is driven low the pass-gate turns on; when released, internal pull-ups raise the line to the respective rail. This enables true bidirectional operation without external control. Typical applications include interfacing microcontrollers with sensors at different voltages, I2C and SMBus bus translation, and UART level shifting between 3.3V and 5V systems in consumer electronics, industrial control, and automotive infotainment. Design tip: ensure VCCA and VCCB stay within specified ranges, control the OE pin to avoid bus contention, and consider the 24 Mbps limit for high-speed links.

TXS0104EQPWRQ1 - 4-Bit Auto-Direction Level Translator | TI
TXS0104EQPWRQ1

TXS0104EQPWRQ1 - 4-Bit Auto-Direction Level Translator | TI

The Texas Instruments TXS0104EQPWRQ1 is an automotive-grade, 4-bit bidirectional voltage-level translator supporting 24 Mbps data rates in a 14-pin TSSOP (PW) package, qualified to AEC-Q100 for -40C to +125C operation. A voltage-level translator (also called a level shifter) is a logic IC that interfaces digital signals between circuits operating at different supply voltages, for example bridging a 1.8V microcontroller to a 5V sensor bus. Translators sit within the broader voltage-translation family of logic ICs, alongside direction-controlled transceivers and unidirectional buffers. The TXS0104E-Q1 belongs to TI's auto-direction TXS family, which requires no host-side direction-control pin. Key features include auto-direction sensing that eliminates the DIR pin entirely, mixed open-drain and push-pull operation per channel, a wide VCCA range of 1.65V to 3.6V and VCCB range of 2.3V to 5.5V, and a 4 kbps to 24 Mbps data-rate window. An active-high OE pin places all I/O in high-impedance during power-up, enabling partial power-down sequencing. Architecturally, the TXS family uses a discrete integration approach with on-chip series resistors and one-shot edge accelerators: the resistors form a passive divider/clamp for open-drain buses while one-shots speed up rising edges for push-pull signals. This makes it tolerant of I2C, SMBus, SPI, UART and GPIO mixed-direction traffic but limits DC drive capability (typ. 2 mA sink at 3.3V side), which distinguishes it from the TXB push-pull-only family. Typical applications include I2C level shifting between 3.3V and 5V domains, automotive infotainment and body-control module GPIO expansion, and mixed-voltage UART/SD-card interfaces. AEC-Q100 qualification suits it for under-hood and cabin electronics. Design consideration: do not use the TXS family where channels source continuous DC current above 2-3 mA or where extremely low standby current is required; the always-on one-shot architecture draws current on every edge.

TXS0108EPWR - 8-Bit Bidirectional Level Shifter 60Mbps | TI
TXS0108EPWR

TXS0108EPWR - 8-Bit Bidirectional Level Shifter 60Mbps | TI

The Texas Instruments TXS0108EPWR is an 8-bit bidirectional voltage-level translator for open-drain and push-pull applications, housed in a 20-pin TSSOP (PW) package. It operates from two independently supplied rails, VCCA (1.2V to 3.6V on the A port) and VCCB (1.65V to 5.5V on the B port), with data rates up to 60 Mbps for push-pull signals and 2 Mbps for open-drain signals. A voltage-level translator, also called a level shifter, is an integrated circuit that enables digital communication between systems operating at different voltage domains. Within the logic-translation hierarchy, bidirectional auto-direction translators such as the TXS0108E sit alongside direction-controlled families like the SN74LVC8T245 and TXB0108, providing mixed-voltage interfacing for microcontrollers, peripherals, and buses. Key features include automatic direction sensing, which eliminates a direction-control pin, and a VCC isolation feature: if either supply rail is at GND, all I/Os enter high impedance, preventing back-powering during partial power-down. Quiescent current is low at 620 uA, and the one-shot accelerator architecture speeds low-to-high transitions for high-speed push-pull operation. The device is specified from -40C to +85C, is RoHS compliant, and carries MSL 1 (260C unlimited floor life). Architecturally, the TXS0108E combines a pull-up based open-drain translation path with edge-accelerating one-shots, making it equally suitable for I2C-style open-drain buses and push-pull SPI/UART links. This auto-direction design trades output drive strength for bidirectionality, so it excels on lightly loaded point-to-point links rather than heavily bused systems. Typical applications include interfacing 1.8V or 3.3V microcontrollers with 5V sensors, SD/MMC memory-card interfaces, UART/SPI/I2C bus translation, and mixed-voltage communication in consumer, industrial, and IoT systems. Design tip: for open-drain use, external pull-up resistors are required on both sides; keep them sized per datasheet recommendations to avoid rise-time degradation at target data rates.

TXS0108EQPWRQ1 - 8-Bit Auto-Direction Level Shifter | TI

The Texas Instruments TXS0108EQPWRQ1 is an automotive-grade, 8-bit bidirectional voltage level translator in a 20-pin TSSOP (PW) package, qualified per AEC-Q100 temperature grade 1 (-40C to +125C). It requires no direction-control signal because its auto-direction sensing architecture detects data flow on each channel independently, supporting both push-pull and open-drain applications. A voltage level translator (also called a logic level shifter or voltage translation IC) is an interface component in the broader logic and interface IC family that safely bridges digital devices operating at different supply domains, for example a 1.8V microcontroller talking to a 5V sensor. Level shifters protect low-voltage I/O from overvoltage while preserving logic thresholds, edge rates, and signal integrity across the voltage boundary. Key specifications include a wide VCCA range of 1.2V to 3.6V and VCCB range of 1.65V to 5.5V, enabling translation between almost any two common logic rails. Push-pull data rates reach 110 Mbps while open-drain operation supports 2 Mbps with integrated 10 kOhm pull-up resistors. The device also offers an OE pin for 3-state operation during power sequencing and classified HBM ESD level 2 and CDM level C6 robustness per TI data. Architecturally, the TXS0108E uses one-shot edge-rate accelerators on each channel to improve rise times, combined with a 4 kOhm series pass-gate element; this open-drain-friendly structure means it is not recommended for applications needing high drive strength such as direct LED loads. Typical applications include automotive infotainment and body-control module I/O translation, sensor and CAN-adjacent digital interfacing, and portable electronics bridging 1.8V/2.5V/3.3V memory or peripheral buses to 5V domains. All prices cited in this page are as of 2026-08-29. Design tip: because of the internal pull-ups, avoid this family for signals requiring low-capacitance backplane conditions; for heavy push-pull loads choose the TXB0108 instead.
