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 2-

to-1 multiplexer/demultiplexer or a quad 2-to1

multiplexer/demultiplexer. The ISL84780 is pin compatible

with the MAX4780.
