Product Overview
The PCA9548APWR from Texas Instruments is an 8-channel I2C-bus multiplexer with reset and interrupt logic. It allows multiple I2C devices with the same address to be connected to a single I2C bus by selectively enabling one of eight downstream channels. The device operates from 2.3V to 5.5V and is available in a 24-pin TSSOP package. It features active-low reset input, three address pins allowing up to eight devices on the same bus, and interrupt inputs for each channel.
