Ultra Low ON-Resistance, Low Voltage, Single Supply, SPDT Analog Switch
The Intersil ISL84714 device is a low ON-resistance, low
voltage, bidirectional, single pole/double throw (SPDT)
Features
• Pb-Free Available (RoHS Compliant)
• Drop In Replacement for the MAX4714
• ON-resistance (r
analog switch designed to operate from a single +1.65V to
+3.6V supply. Targeted applications include battery powered
equipment that benefit from low ON-resistance and fast

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
ISL84714 is offered in the 6 Ld SC70 package, alleviating
board space limitations.

The ISL84714 is a committed SPDT that consists of one
normally open (NO) and one normally closed (NC) switch.
This configuration can also be used as a 2-to-1 multiplexer.
