Description

The Intersil ISL54057 device contains precision, bidirectional, analog switches configured as a differential 4-channel multiplexer/demultiplexer, designed to operate from a single +1.6V to +3.6V supply. The devices have an inhibit pin to simultaneously open all signal paths. ON resistance is 0.41 with a +3V supply and 0.61 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 or 35nA max at +85C with a +3.3V supply. All digital inputs are 1.8V logic-compatible when using a single +3V supply. The ISL54057 is a differential 4 to 1 multiplexer device that is offered in a 16 Ld 2.6x1.8x0.5mm TQFN package.
