DATASHEET
ISL84524, ISL84525
Low-Voltage, Single Supply, 4 to 1 Multiplexer and DPDT Analog Switches
The Intersil ISL84524 and ISL84525 devices are precision,
bidirectional, analog switches configured as a 4 channel
multiplexer/demultiplexer (ISL84524) and a double
pole/double throw (DPDT) switch (ISL84525) designed to
operate from a single +2V to +12V supply. Both have an
inhibit pin to simultaneously open all signal paths.
ON resistance is 200О© with a +5V supply and 500О© with a
+3V supply. Each switch can handle rail-to-rail analog
signals. The off-leakage current is only 1nA at +25В°C or
25nA 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.
The ISL84524 is a 4 to 1 multiplexer device. The ISL84525 is
a DPDT, which is perfect for use in 2-to-1 multiplexer
applications.
Table 1 summarizes the performance of this family. For
higher performance, see the ISL43640 and ISL43410 data
sheets.
