TCA9548ADGSR TI I2C Switch/Multiplexer | 24-VSSOP | 8-Channel, 1.65-5.5V

Product Overview

The TCA9548ADGSR is a low-voltage 8-channel I2C switch/multiplexer from Texas Instruments, designed for applications requiring multiple I2C buses with the same address. It allows up to eight downstream I2C buses to be selected via the I2C bus, enabling communication with multiple devices sharing the same address. The device operates from 1.65V to 5.5V, making it suitable for both low-voltage and standard systems. Housed in a compact 24-VSSOP package, it is ideal for space-constrained designs.
