Ultra Low ON-Resistance, +1.65V to +4.5V, Single Supply, Dual SPDT Analog  
Switch  
The Intersil ISL8484 device is a low ON-resistance, low  
voltage, bidirectional, dual single-pole/double-throw (SPDT)  
Features  
• Pin Compatible Replacement for the MAX4684 and  
MAX4685  
analog switch designed to operate from a single +1.65V to  
+4.5V supply. Targeted applications include battery powered  
equipment that benefit from low r

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 part may be used to “mux-in”  
additional functionality while reducing ASIC design risk. The  
ISL8484 is offered in small form factor packages, alleviating  
board space limitations.

The ISL8484 is a committed dual single-pole/double-throw  
(SPDT) that consist of two normally open (NO) and two  
normally closed (NC) switches. This configuration can be  
used as a dual 2-to-1 multi-plexer. The ISL8484 is pin  
compatible with the MAX4684 and MAX4685.  
• 1.8V Logic Compatible (+3V supply)  
• Low I+ Current when V H is not at the V+ Rail
