Low-Voltage, Single and Dual Supply, 8 to 1 Multiplexer and Differential 4 to 1 Multiplexer

The Intersil ISL43681 and ISL43741 devices are precision, bidirectional, analog switches configured as an 8 channel and a differential 4 channel multiplexer/demultiplexer. They are designed to operate from a single +2V to +12V supply or from a ±2V to ±6V supplies. The devices have an inhibit and inhibit bar pin to simultaneously open all signal paths. The devices also have a latch bar pin to lock in the last switch address.
