DATASHEET  
ISL43120, ISL43121, ISL43122  
Low-Voltage, Single Supply, Dual SPST Analog Switches

Aug 17, 2015  
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  
Features  
• Fully specified at 12V, 5V, and 3.3V supplies for 10%  
tolerances

• Single supply operation . . . . . . . . . . . . . . . . . . . . . . +2.7V to +12V  
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.

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.  
• Guaranteed break-before-make (ISL43122 only)  
• Minimum 2000V ESD protection per method 3015.7
