ISL43120, ISL43121, ISL43122, ISL43210
Low-Voltage, Single Supply, Dual SPST,
SPDT Analog Switches
The Intersil ISL43120, ISL43121, ISL43122 and ISL43210
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 (5
W), low
leakage currents (100pA max), and fast switching speeds
(t
ON
= 28ns, t
OFF
= 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. The ISL43210 is a
committed SPDT, which is perfect for use in 2-to-1 multiplexer
applications.
