Ultra Low ON-Resistance, Low Voltage,  
Single Supply, Dual SPDT Analog Switch  
in Chipscale Package  
The Intersil ISL84684II device is a low ON-resistance, low  
voltage, bidirectional, dual single-pole/double-throw (SPDT)  
analog switch designed to operate from a single +1.8V to  
+4.5V supply. Targeted applications include battery powered  
Features

MAX4685

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  
ISL84684II is offered in a 2.00mm x 1.50mm chipscale  
package, alleviating board space limitations. The 4x3 array of  
solder balls are spaced with a 0.5mm ball pitch.

The ISL84684II 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 multiplexer. The ISL84684II is pin  
compatible with the MAX4684 and MAX4685.  
• Low I+ Current when VinH is not at the V+ Rail
