  Description

The Intersil ISL84781 device contains precision, bidirectional analog switches configured as an 8-channel multiplexer/demultiplexer. It is designed to operate from a single +1.6V to +3.6V supply. The device has an inhibit pin to simultaneously open all signal paths.

ON resistance is 0.4Ω with a +3.0V supply and 0.55Ω with a single +1.8V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 4nA max at +25oC or 40nA max at +85oC with a +3.3V supply.

All digital inputs are 1.8V logic-compatible when using a single +3V supply.

The ISL84781 is a 8 to 1 multiplexer device that is offered in a 16 Ld TSSOP package, and a 16 Ld thin QFN package.
