Product Introduction

Overview

The TXB0104PWR, produced by Texas Instruments, is a 4-bit bidirectional voltage-level translator designed to facilitate communication between devices operating at different voltage levels. This IC uses two separate configurable power-supply rails, allowing for universal low-voltage bidirectional translation between various voltage nodes such as 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V. The device features auto direction sensing, eliminating the need for a direction control signal, and includes robust ESD protection and low power consumption, making it suitable for a wide range of applications.
