TCA9548APWR TI I2C Switch/Multiplexer | 24-TSSOP | 8-Channel, 1.65-5.5V

Product Overview

The TCA9548APWR from Texas Instruments is an 8-channel I2C-bus switch/multiplexer with reset, designed for applications requiring multiple I2C devices with the same address. It allows up to eight downstream I2C buses to be selected individually or in combination, enabling flexible communication in complex systems. Housed in a compact 24-TSSOP package, it operates over a wide voltage range of 1.65V to 5.5V, making it suitable for both low-voltage and standard logic systems. The device features active-low reset input, three address pins allowing up to 8 devices on the same bus, and low standby current consumption.
