Data Sheet
ISL84524, ISL84525
June 2003
FN6042.1
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 200Ω with a +5V supply and 500Ω with a
+3V supply. Each switch can handle rail to rail analog
signals. The off-leakage current is only 1nA at +25oC or
25nA at +85oC.
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.
