DATASHEET
ISL5120, ISL5121, ISL5122, ISL5123
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
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 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.
