Low-Voltage, Single Supply, Dual SPST,

SPDT Analog Switches

The Intersil ISL5120, ISL5121, ISL5122, ISL5123 devices are

precision, bidirectional, dual analog 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 (t

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 ISL5120, ISL5121, ISL5122 are dual single-pole/single-

throw (SPST) devices. The ISL5120 has two normally open

(NO) switches; the ISL5121 has two normally closed (NC)

switches; the ISL5122 has one NO and one NC switch and

can be used as an SPDT. The ISL5123 is a committed SPDT,

which is perfect for use in 2-to-1 multiplexer applications.
