This device can handle both digital and analog signals, and signals up to V+ can be transmitted in either direction. The TS3A27518E has two control pins, each controlling three 1-of-2 muxes at the same time, and an enable pin that is used to put all outputs in high-impedance mode. The control pins are compatible with 1.8V logic thresholds and are backward compatible with 2.5 V and 3.3 V logic thresholds as well. The TS3A27518E allows any SD, SDIO, and multimedia card host controllers to be expanded out to multiple cards or peripherals since 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.
