ISL43L410
FN6090.1
Ultra Low ON-Resistance, Low Voltage,
Single Supply, DPDT Analog Switch
The Intersil ISL43L410 device is a low ON-resistance, low
voltage, bidirectional, double-pole/double-throw (DPDT)
analog switch designed to operate from a single +1.65V to
+3.6V supply. It is equipped with an inhibit pin to
simultaneously open all signal paths.
Targeted applications include battery powered equipment that
benefit from low R_ON (0.25Ω) and fast switching speeds
(t_ON = 12ns, 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
ISL43L410 is offered in small form factor packages, alleviating
board space limitations.
The ISL43L410 is a committed double-pole/double-throw
(DPDT) that consists of two normally open (NO) and two
normally closed (NC) switches. This configuration is perfect
for use in differential 2-to-1 multiplexer applications.
