Overview

The TXB0106QWBQBRQ1 is an automotive-qualified 6-bit bidirectional voltage-level translator featuring two independent configurable power-supply rails. It allows for seamless data transfer between components operating at different logic levels, supporting VCCA from 1.2 V to 3.6 V and VCCB from 1.65 V to 5.5 V. This AEC-Q100 qualified device utilizes an auto-direction sensing architecture, eliminating the need for a direction-control signal.

Why Choose This Part

The device features a push-pull, tri-state output capable of supporting data rates up to 100Mbps. Its automotive qualification includes wettable flank packaging for improved automated optical inspection and VCC isolation to ensure all outputs are in a high-impedance state if either VCC input is grounded.

Applications

Automotive Telematics
Interfacing low-voltage application processors with 5V automotive sensors or communication modules.
ADAS Sensor Fusion
Level shifting high-speed data signals between radar modules and central processing units.
Infotainment Systems
Bridging 1.8V or 3.3V microcontrollers with legacy 5V peripheral buses in vehicle head units.
HVAC Control Units
Translating logic levels between climate control sensors and the main system MCU.

Getting Started

When designing with this part, ensure the VCCA supply voltage is always less than or equal to VCCB. Place 0.1 uF decoupling capacitors as close to the VCCA and VCCB pins as possible to maintain signal integrity at high data rates. The OE pin should be tied to VCCA through a pull-down resistor to ensure the high-impedance state during power-up or power-down.
