TITXS0104VQBQARQ1

Overview

The TXS0104VQBQARQ1 is an automotive-qualified 4-bit bidirectional voltage level translator designed for interfacing modern low-voltage processors with higher-voltage peripherals. It supports data rates up to 24 Mbps and features an auto-direction sensing architecture that eliminates the need for a dedicated direction-control pin. This AEC-Q100 qualified device is ideal for mixed-voltage systems ranging from 1.65V to 5.5V.

Why Choose This Part

This device uses an auto-sensing architecture which simplifies PCB routing and reduces GPIO count by removing the need for a DIR signal. It features wettable flanks for automated optical inspection (AOI) in automotive manufacturing and provides robust ESD protection exceeding JESD 22 standards. The ability to handle both push-pull and open-drain logic makes it a versatile solution for varied interface types.

Applications

Getting Started

When designing with this part, ensure VCCA is always less than or equal to VCCB and that both supplies are properly bypassed with 0.1uF capacitors. For prototyping, utilize the Texas Instruments TXS0104EVM evaluation module to verify signal integrity at various voltage combinations. The OE (Output Enable) pin should be tied to GND through a pull-down resistor to ensure a high-impedance state during power-up.
