FN6093.2
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_ON (0.22Ω) and fast
switching speeds (t_ON = 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.
