The Intersil ISL84714 device is a low ON-resistance, low

voltage, bidirectional, single pole/double throw (SPDT)

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

switching speeds (tON = 7.5ns, tOFF = 2.9ns). The digital logic

input is 1.8V CMOS compatible when using a single +3V

supply.

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
