The TS3A27518E-Q1 is a 6-bit 1-of-2 mux/demux designed to operate from 1.65 V to 3.6 V. This device can handle both digital and analog signals, and signals up to V+ can be transmitted in either direction. The TS3A27518E-Q1 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 1.8-V logic thresholds and are backward compatible with 2.5-V and 3.3-V logic thresholds as well.
The TS3A27518E-Q1 allows any SD, SDIO, and multimedia card host controllers to be expanded out to multiple cards or peripherals because the SDIO interface consists of 6-bits: CMD, CLK, and Data[0:3] signals. The TS3A27518E-Q1 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.
