Ultra Low ON-Resistance, Low-Voltage,

Single Supply, Differential 4 to 1 Analog

Multiplexer

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

+25°C and 30nA max at +85°C 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

package.
