Low-Voltage, Single and Dual Supply,  
Triple SPDT Analog Switch  
Features  
• Fully Specified at 3.3V, 5V, ±5V, and 12V Supplies for 10%  
Tolerances  
The Intersil ISL43231 device is a precision, bidirectional,  
analog switch configured as a a triple single pole/double throw  
(SPDT) switch, designed to operate from a single +2V to  
+12V supply or from a ±2V to ±6V supply. The device has an  
inhibit and inhibit bar pin to simultaneously open all signal  
paths. The device also has a latch bar pin to lock in the last  
switch address.
