TCA9545APWR TI I2C Switch/Multiplexer | 20-TSSOP | 4-Channel, 1.65-5.5V

Product Overview

The TCA9545APWR from Texas Instruments is a 4-channel I2C switch/multiplexer with reset functionality, designed for voltage translation between 1.65V and 5.5V. It allows multiple I2C devices with the same address to be connected to a single bus by selectively enabling one channel at a time. The device features active-low reset input and three address pins, allowing up to eight devices on the same bus. Housed in a 20-pin TSSOP package, it is ideal for applications requiring bus isolation or voltage level shifting.
