Features
• Fully specified at 12V, 5V, and 3.3V supplies for 10%
tolerances
The Intersil ISL43120, ISL43121 and ISL43122 devices are
precision, bidirectional, dual analog SPST switches designed
to operate from a single +2.7V to +12V supply. Targeted
applications include battery powered equipment that benefit
from the devices’ low power consumption (5µW), low leakage

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. Some of the smallest packages are available,
alleviating board space limitations, and making Intersil’s
newest line of low-voltage switches an ideal solution.

The ISL43120, ISL43121, ISL43122 are dual
single-pole/single-throw (SPST) devices. The ISL43120 has
two normally open (NO) switches; the ISL43121 has two
normally closed (NC) switches; the ISL43122 has one NO
and one NC switch and can be used as an SPDT.
• Available in SOT-23 packaging
• Pb-Free Available (RoHS Compliant)
