ISL43640
Low-Voltage, Single Supply, 4 to 1 Multiplexer, High Performance Analog Switch FN6043
Rev 3.00
Jan 23, 2006 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. Features ON resistance is 115пЃ— with a +5V supply, 45пЃ— with a +12V
supply, and 190пЃ—пЂ with a +3V supply. Each switch can handle
rail to rail analog signals. The off-leakage current is only 1nA
at 25В°C or 2.5nA at 85В°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. RON Matching Between Channels <2пЃ— Table 1 summarizes the performance of this switch.
