Data Sheet March 28, 2007

Ultra Low ON-Resistance, +1.65V to +4.5V ,
Single Supply, Dual SPDT Analog Switch

The Intersil ISL54050 device is a low ON-resistance, low
voltage, bidirectional, dual single-pole/double-throw (SPDT)
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
switching speeds (t

input is 1.8V logic-compatible when using a single +3V supp ly.
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
ISL54050 is offered in small form factor package, alleviating
board space limitations.

The ISL54050 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 ISL5 4050 is pin
compatible with the NLAS5223 and NLAS5223L.
