Overview
The TS3A27518E-Q1 is a 6-bit, 1-of-2 multiplexer-demultiplexer designed by Texas Instruments. This device operates from a single supply voltage of 1.65 V to 3.6 V and is capable of handling both digital and analog signals. It features two control pins, each controlling three 1-of-2 multiplexers simultaneously, and an enable pin to put 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 device is particularly useful for expanding SD, SDIO, and multimedia card host controllers to multiple cards or peripherals.
