FN6043.1
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 25oC or 2.5nA at 85oC. 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
Intersilâs newest line of low-voltage switches an ideal solution.
Table 1 summarizes the performance of this switch.
