TCA9548ARGERQ1 TI Multiplexer | 24-VQFN (4x4) | 1.65-5.5V, 8-Channel I2C

Product Overview

The TCA9548ARGERQ1 is a low-voltage, 8-channel I2C bus switch/multiplexer from Texas Instruments, designed for automotive applications. It allows multiple I2C devices with the same address to be connected to a single bus by selectively enabling one channel at a time. Operating from 1.65V to 5.5V, it supports standard (100 kHz) and fast (400 kHz) I2C modes. The device is qualified to AEC-Q100 for automotive reliability.
