TCA9548ARGERQ1 TI I2C Switches, Multiplexers

This automotive-grade 8-channel I2C multiplexer with reset and interrupt from Texas Instruments operates from 1.65V to 5.5V with AEC-Q100 qualification, allowing up to eight downstream buses from a single master. For selection, it features individual channel enables, an active-low reset for hardware initialization, interrupt inputs with combined output, and standby current below 1µA, operating across -40°C to +125°C. In application, it excels in multi-camera automotive surround-view systems aggregating image sensor I2C buses, battery management units monitoring eight cell modules, in-cabin sensor hubs for temperature, humidity, and occupant detection, and ADAS controller peripheral expansion. It is also widely used in automotive infotainment head units, telematics control modules, body domain controllers, and any automotive electronics requiring I2C bus isolation and address expansion.
