ISL84684
Ultra Low ON-Resistance, Low Voltage,
Single Supply, Dual SPDT Analog Switch
The Intersil ISL84684 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
+3.6V supply. Targeted applications include battery powered
equipment that benefits from low r
ON
(0.35Ω) and fast
switching speeds (t
ON
=50ns, t
OFF
= 27ns). 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
ISL84684 is offered in small form factor packages, alleviating
board space limitations.
The ISL84684 is a committed dual single-pole/double-throw
(SPDT) that consists of two normally open (NO) and two
normally (NC) switches. This configuration can be used as a
dual 2-to-1 multiplexer. The ISL84684 is pin compatible with
the MAX4684 and MAX4685.
