The TS3A27518E is a bidirectional, 6-channel,
1:2 multiplexer-demultiplexer designed to operate from 1.65 V to
3.6 V. This device can handle both digital and analog signals, and can transmit signals up to
VCC in either direction. The TS3A27518E has two control pins, each
controlling three 1:2 muxes at the same time, and an enable pin that 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.
The TS3A27518E allows any SD, SDIO, and multimedia card host controllers to expand out to
multiple cards or peripherals because the SDIO interface consists of 6-bits: CMD, CLK, and
Data[0:3] signals. The TS3A27518E has two control pins that give additional flexibility to the
user. For example, the ability to mux two different audio-video signals in equipment such as an LCD
television, an LCD monitor, or a notebook docking station.
