Overview

The TXS0102QDCURQ1 is an AEC-Q100 qualified, 2-bit bidirectional voltage level translator designed for applications requiring auto-direction sensing. It supports communication between different logic voltage levels, ranging from 1.65V to 3.6V on Port A and 2.3V to 5.5V on Port B, without the need for a dedicated direction control signal. This automotive-grade component is ideal for interfacing low-voltage microcontrollers with higher-voltage peripherals or buses.

Why Choose This Part

The device eliminates the need for a direction-control pin, simplifying PCB routing and reducing MCU pin count requirements. It features built-in edge-rate accelerators to support up to 24Mbps in push-pull mode and 2Mbps in open-drain mode. Additionally, its AEC-Q100 qualification ensures reliability in harsh automotive environments with no specific power-supply sequencing required.

Applications

I2C Level Shifting
Translating SDA and SCL signals between 1.8V processors and 5V sensors or EEPROMs in automotive systems.
1-Wire Interfacing
Bidirectional voltage translation for 1-Wire protocol devices used in battery management or identification modules.
General GPIO Translation
Connecting low-voltage SoC digital outputs to high-voltage industrial or automotive logic inputs up to 24Mbps.
Open-Drain Bus Support
Ideal for multi-master bus environments where pull-up resistors are required for signal integrity.

Getting Started

To implement this part, connect VCCA to the lower voltage supply and VCCB to the higher voltage supply, ensuring VCCA is always less than or equal to VCCB. Place 0.1uF decoupling capacitors near the supply pins and pull the OE pin high to enable the device. For prototyping, look for universal VSSOP-8 breakout boards or the TXS0102EVM evaluation module from Texas Instruments.
