TCA9544APWR TI Multiplexer | 20-TSSOP | 4-Channel I2C, 1.65-5.5V

Product Overview

The TCA9544APWR is a 4-channel I2C multiplexer from Texas Instruments, designed to enable multiple I2C slave devices with the same address to be connected to a single I2C bus. It operates over a wide supply 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 and three address pins, allowing up to eight devices on the same bus. Housed in a compact 20-TSSOP package, it is ideal for space-constrained applications.
