Overview
The TS3A27518E, produced by Texas Instruments, is a bidirectional, 6-channel, 1:2 multiplexer-demultiplexer. This device is designed to operate from 1.65 V to 3.6 V and can handle both digital and analog signals. It features two control pins, each controlling three 1:2 multiplexers, and an enable pin that places all outputs in high-impedance mode. The control pins are compatible with 1.8-V logic thresholds and are backward compatible with 2.5-V and 3.3-V logic thresholds. This versatility makes it suitable for a variety of applications, including signal routing in audio, video, and data interfaces.
