TEXAS INSTRUMENTS TS3A27518ERTWR

The TS3A27518ERTWR is a 1:2 Multiplexer/Demultiplexer that can handle both digital and analog signals and can transmit signals up to VCC in either direction. The device 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 1.8V logic thresholds and are backward compatible with 2.5V and 3.3V logic thresholds. The device allows any SD, SDIO and multimedia card host controllers to expand out to multiple cards or peripherals because the SDIO interface consists of 6-bit, CMD, CLK and data [0:3] signals. The device 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.
