ISL43L220

Ultra Low ON-Resistance, Low Voltage,

Single Supply, Dual SPDT Analog Switch

The Intersil ISL43L220 device is a low ON-resistance, low

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

analog switch designed to operate from a single +1.1V to

+4.5V supply. Targeted applications include battery powered

equipment that benefit from low R

(0.22Ω) and fast

switching speeds (t

= 11ns, t

OFF

= 5ns). 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

ISL43L220 is offered in a small form factor package,

alleviating board space limitations.

The ISL43L220 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 also be

used as a dual 2-to-1 multiplexer. The ISL43L220 is pin

compatible with the MAX4684 and MAX4685.
