ISL84781
Ultra Low ON-Resistance, Low-Voltage,
Single Supply, 8-to-1 Analog Multiplexer
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.
All digital inputs are 1.8V logic-compatible when using a
single +3V supply.
The ISL84781 is a 8-to-1 multiplexer device that is offered in a
16 Ld TSSOP package, and a 16 Ld thin QFN package.
Table 1 summarizes the performance of this family.
