ISL54053

Ultra Low ON-Resistance, Low Voltage,

Single Supply, SPDT Analog Switch

The Intersil ISL54053 device is a low ON-resistance, low

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

analog switch designed to operate from a single +1.8V to

+5.5V supply. Targeted applications include battery powered

input is 1.8V logic compatible when using a single +3.0V

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

ISL54053 is offered in the 6 Ld 1.2mmx1.0mmx0.5mm

µTDFN package, alleviating board space limitations.

The ISL54053 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.
