PCA9548ADBR TI I2C Multiplexer | 24-SSOP | 8-Channel, 2.3V-5.5V

Product Overview

The PCA9548ADBR from Texas Instruments is an 8-channel I2C-bus multiplexer with reset functionality. It allows up to eight I2C slave devices with the same address to be connected to a single I2C bus by selectively enabling one channel at a time. The device operates from 2.3V to 5.5V and is available in a compact 24-SSOP package, making it ideal for multi-address I2C bus expansion in complex systems.
