ISL43640
Low-Voltage, Single Supply, 4 to 1
Multiplexer, High Performance Analog
Switch
The Intersil ISL43640 is a precision, bidirectional, analog
switch configured as a 4 channel multiplexer/demultiplexer.
The ISL43640 is designed to operate from a single +2V to
+12V supply. It is equiped with an inhibit pin to simultaneously
open all signal paths.
ON resistance is 115
with a +5V supply, 45
with a +12V
supply, and 190
with a +3V supply. Each switch can handle
rail to rail analog signals. The off-leakage current is only 1nA
at 25
o
C or
2.5
nA at 85
o
C. All digital inputs have
0.8V
to
2.4V
logic
thresholds ensuring TTL/CMOS logic compatibility when using a
single
+5V supply. Some of the smallest packages are
available, alleviating board space limitations, and making
Intersil's newest line of low-voltage switches an ideal solution.
Table 1 summarizes the performance of this switch.
