Overview

The TXS0108EQPWRQ1 is an automotive-qualified, eight-bit bidirectional voltage-level translator from Texas Instruments. It lets you shift digital signal levels between different logic domains on an 8-bit bus. The part is intended for general-purpose digital interfaces in automotive and industrial systems.

Why Choose This Part

This part provides eight independent bidirectional channels in a single small package, saving board area compared with discrete solutions. It is offered in an automotive-grade (Q1) variant, which simplifies selection for vehicle systems that require AEC-Q100 qualification. Using an integrated translator reduces BOM and layout complexity compared with multiple single-channel translators or resistor networks.

Applications

MCU-to-sensor interfacing
Shift GPIO and peripheral signal levels when connecting microcontrollers to sensors or modules that use a different IO voltage.
Module integration
Bridge logic levels between vehicle telematics or comms modules and domain controllers or non-matching expansion boards.
Mixed-voltage digital buses
Level-translate 8-bit parallel or multiplexed buses between voltage domains during board redesigns or when reusing legacy components.
Automotive electronic control units (ECUs)
Use in ECUs to interface low-voltage controllers with higher-voltage peripherals while meeting automotive reliability requirements.

Getting Started

Start by reading the TI datasheet and application notes for recommended decoupling and layout guidelines and to confirm compatibility with your bus type. The device requires powering both voltage domains; verify supply sequencing and absolute maximum ratings on the datasheet. For prototyping, use a breakout or place the device on a small adapter so you can test each channel and confirm signal integrity before final PCB design.
