DATASHEET
ISL43120, ISL43121, ISL43122
Low-Voltage, Single Supply, Dual SPST Analog Switches
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
currents (100pA max) and fast switching speeds (tON = 28ns,
tOFF = 20ns). 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. 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.
