ISL43L840 Ultra Low ON-Resistance, Low-Voltage, Single Supply, Dual 4 to 1 Analog Multiplexer

The Intersil ISL43L840 device is a precision, bidirectional, analog switches configured as a dual 4-channel multiplexer/demultiplexer, designed to operate from a single +1.6V to +3.6V supply.

ON resistance is 0.5Ohm with a +3V supply and 0.62Ohm 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 ISL43L840 is a dual 4 to 1 multiplexer device that is offered in a 16 Ld TSSOP and 16 Ld 3x3 QFN packages.
