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 rON (0.29Ω) and fast

switching speeds (tON = 40ns, tOFF = 20ns). The digital logic

input is 1.8V logic-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

ISL54050 is offered in small form factor package, alleviating

board space limitations.

The ISL54050 is a committed dual single-pole/double-throw

(SPDT) that consists of two normally open (NO) and two

normally closed (NC) switches. This configuration can be

used as a dual 2-to-1 multiplexer. The ISL54050 is pin

compatible with the NLAS5223 and NLAS5223L.
