Overview

The TXS0108EQWRKSRQ1 is an automotive-qualified (AEC-Q100) 8-bit bidirectional voltage level translator designed for multi-voltage digital systems. It features an auto-direction sensing architecture that eliminates the need for a direction-control signal, making it ideal for interfacing legacy 5V logic with modern low-voltage microcontrollers. This device supports data rates up to 110Mbps and is housed in a 20-pin VQFN package with wettable flanks for enhanced solder joint inspection.

Why Choose This Part

This translator requires no power-supply sequencing and supports a wide VCCA range of 1.4V to 3.6V and VCCB range of 1.65V to 5.5V. Its auto-direction sensing simplifies PCB routing by removing the need for GPIO-based direction control. The AEC-Q100 qualification and wettable flank package ensure high reliability in harsh automotive environments.

Applications

Automotive Infotainment
Bridging low-voltage application processors with 5V peripheral modules or display controllers.
ADAS Sensor Interfacing
Level shifting between 1.8V sensors and 3.3V or 5V automotive control units.
I2C and SPI Level Shifting
Translating open-drain or push-pull serial communications across different voltage domains.
Body Control Modules
Interfacing 1.4V to 3.6V internal logic with 5V external communication transceivers.

Getting Started

When designing with this part, ensure the VCCA supply is always less than or equal to VCCB. Place bypass capacitors close to the VCC pins and note that the OE pin should be tied to GND through a pull-down resistor to ensure high-impedance state during power-up or power-down.
