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 equipped 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°C or 2.5nA at 85°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.
