Low-Voltage, Single and Dual Supply,  
Quad SPST, High Performance Analog  
Switches  
Features  
• Fully Specified for 10% Tolerances at V = ±5V and  
V+ = 12V, 5V and 3.3V  
S
The Intersil ISL43143–ISL43145 devices are CMOS,  
• Four Separately Controlled SPST Switches  
• Pin Compatible with DG411/DG412/DG413  
precision, quad SPST analog switches designed to operate  
from a single +2V to +12V supply or from a ±2V to ±6V supply.  
Targeted applications include battery powered equipment that  
benefit from the devices’ low power consumption (<1µW), low  
leakage currents (5nA max), and fast switching speeds

• Fast Switching Action  
The ISL43143/ISL43144/ISL43145 are quad single-pole/  
single-throw (SPST) devices. The ISL43143 has four normally  
closed (NC) switches; the ISL43144 has four normally open  
(NO) switches; the ISL43145 has two NO and two NC  
switches and can be used as a dual SPDT, or a dual 2:1  
multiplexer.
