3 Description
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 V_CC 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.
