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

The Intersil ISL84581 device contains precision, bidirectional, analog switches configured as an 8-to-1 multiplexer/demultiplexer. It was designed to operate from a single +2V to +12V single supply or from dual ±2V to ±6V supplies. The device has an inhibit pin to simultaneously open all signal paths.
