TS3A27518E Multiplexer/Demultiplexers Texas Instruments TS3A27518E Multiplexer/Demultiplexer with integrated IEC L-4 ESD and 1.8V logic compatible control inputs are designed to operate from 1.65V to 3.6V. The TI TS3A27518E can handle both digital and analog signals and features a bandwidth up to 240 MHz for high-speed rail-to-rail signal handling. This TI device allows signals up to V+ to be transmitted in either direction. The TI TS3A27518E multiplexer/demultiplexer has two control pins that each control 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 2.5V and 3.3V logic thresholds as well.
