Product Introduction

Overview

The TCA9548AMRGER is a low-voltage 8-channel I2C switch manufactured by Texas Instruments. This component is designed to address the challenges of I2C address conflicts by enabling the connection of multiple I2C devices with identical addresses to a single I2C bus. It is widely used in applications requiring I2C bus expansion, such as industrial automation, consumer electronics, and IoT devices. The TCA9548AMRGER is particularly valued for its ability to support up to eight independent I2C channels, making it an ideal solution for complex systems with multiple I2C peripherals.
