Description

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 25C or 2.5nA at 85C. 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 Intersils newest line of low-voltage switches an ideal solution.
