ISL43L420
Ultra Low ON-Resistance, +1.1V to +4.5V
Single Supply, Quad SPDT (Dual DPDT)
Analog Switch
The Intersil ISL43L420 device is a low ON-resistance, low
voltage, bidirectional, Quad SPDT (Dual DPDT) 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
(0.24
)
and fast
switching speeds (t
ON
= 8ns, 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
ISL43L420 is offered in a small form factor package,
alleviating board space limitations.
The ISL43L420 is a committed Quad SPDT that consists of
four normally open (NO) and four normally (NC) switches.
This configuration can also be used as a diff dual 2-to-1
multiplexer/demultiplexer or a dual 2-to1
multiplexer/demultiplexer. The ISL43L420 is pin compatible
with the STG3699.
