TCA9548ARGER TI I2C Switch/Multiplexer | 24-VQFN (4x4) | 1.65V-5.5V, 8-Channel

Product Overview

The TCA9548ARGER from Texas Instruments is an 8-channel I2C switch/multiplexer designed for applications requiring multiple I2C buses with the same address. It allows voltage level translation between 1.8V, 2.5V, 3.3V, and 5V buses, making it ideal for mixed-voltage systems. The device is housed in a compact 24-VQFN (4x4 mm) package, saving board space.
