ISL8484
Ultra Low ON-Resistance, +1.65V to +4.5V,
Single Supply, Dual SPDT Analog Switch
The Intersil ISL8484 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.
With a supply voltage of 4.2V and logic high voltage of 2.85V
at both logic inputs, the part draws only 12A max of I+
current.
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
ISL8484 is offered in small form factor packages, alleviating
board space limitations.
The ISL8484 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 be
used as a dual 2-to-1 multi-plexer. The ISL8484 is pin
compatible with the MAX4684 and MAX4685.
