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 digital and analog signals and can transmit signals up to VCC in either direction. The TS3A27518E has two control pins, each of which can simultaneously control three 1:2 multiplexers, and one enable pin that can place all outputs in the high-impedance mode. This control pin is compatible with 1.8-V logic thresholds and is backward compatible with 2.5-V and 3.3-V logic thresholds. Since the SDIO interface contains 6-bit signals, namely CMD, CLK, and data [0:3] signals, the TS3A27518E allows SD, SDIO, and multimedia card host controllers to expand to multiple cards or peripherals. This device also supports other 6-bit interfaces such as qSPI. The TS3A27518E has two control pins, providing users with greater flexibility. For example: the device can multiplex two different audio-video signals in devices such as LCD TVs, LCD monitors, or laptop docking stations.
