Description

The Intersil ISL84782 device contains precision, bidirectional, analog switches configured as a differential 4-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 0.5 with a +3V supply and 0.62 with a single +1.8V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 4nA max at +25C and 30nA max at +85C with a +3.3V supply. All digital inputs are 1.8V logic-compatible when using a single +3V supply. The ISL84782 is a differential 4 to 1 multiplexer device that is offered in a 16 Ld TSSOP package and a 16 Ld thin QFN
