FN6095.2

Ultra Low ON-Resistance, Low-Voltage,

Single Supply, 8 to 1 Analog Multiplexer

Features

• Pin Compatible Replacement for the MAX4781, and

MAX4617

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

+25°C or 40nA max at +85°C with a +3.3V supply.
