TS3A27518ERTWR

The TS3A27518E is a bidirectional 6-channel 1:2 multiplexer/demultiplexer designed to operate at 1.65V to 3.6V. This device handles both digital and analog signals, and can pass signals up to VCC in either direction. The TS3A27518E has two control pins, each simultaneously controlling three 1:2 multiplexers, along with an enable pin that places all outputs into 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. Since the SDIO interface contains 6-bit signals — CMD, CLK, and Data[0:3] — the TS3A27518E allows SD, SDIO, and multimedia card host controllers to expand to multiple cards or peripherals. The device also supports other 6-bit interfaces such as qSPI. The TS3A27518E features two control pins, providing greater flexibility for users. For example, the device can multiplex two different audio-video signals in applications such as LCD TVs, LCD monitors, or laptop docking stations.
