Data Sheet

Ultra Low ON-Resistance, Low Voltage,
Single Supply, Quad 2:1 Analog
Multiplexer

The Intersil ISL84780 device is a low ON-resistance, low
voltage, bidirectional, Quad SPDT (Dual DPDT) analog
switch designed to operate from a single +1.6V to +3.6V
supply. Targeted applications include battery-powered
equipment that benefit from low on-resistance, and fast
switching speeds (t
input is 1.8V logic-compatible when using a single +3V supply.

Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This family of parts may be used to
“mux-in” additional functionality while reducing ASIC design
risk. The ISL84780 is offered in small form factor packages,
alleviating board space limitations.

The ISL84780 is a committed Quad SPDT that consists of
four normally open (NO) and four normally closed (NC)
switches. This configuration can also be used as a diff dual 2­to-1 multiplexer/demultiplexer or a quad 2-to1
multiplexer/demultiplexer. The ISL84780 is pin compatible
with the MAX4780.
