TITXB0106QWBQBRQ1

Overview

The TXB0106QWBQBRQ1 is an automotive-qualified 6-bit bidirectional voltage-level translator that uses two separate configurable power-supply rails. It is designed to bridge the logic gap between legacy 5V systems and modern low-voltage microcontrollers or sensors in harsh vehicle environments. The device features automatic direction sensing, which eliminates the need for a dedicated direction-control signal from the host processor.

Why Choose This Part

The device is AEC-Q100 qualified for automotive applications and supports a wide VCCA/VCCB range from 1.2V to 3.6V and 1.65V to 5.5V respectively. Its auto-direction sensing architecture simplifies PCB routing and reduces GPIO pin usage on the MCU. Integrated ESD protection ensures robust performance against the electrical transients common in automotive subsystems.

Applications

Getting Started

When designing with this part, ensure that the VCCA supply voltage is always less than or equal to VCCB. Place decoupling capacitors as close to the VCCA and VCCB pins as possible to maintain signal integrity during high-speed transitions. For evaluation, use a standard breadboard adapter or integrate the chip into a prototype using the 12-pin DQFN footprint.
