Low-Voltage, Single and Dual Supply, 8 to
1 Multiplexer, Dual 4 to 1 Multiplexer and a
Triple SPDT Analog Switches
The Intersil ISL84051, ISL84052, ISL84053 devices are
precision, bidirectional, analog switches configured as a 8
channel multiplexer/demultiplexer (ISL84051), a dual
differential 4 channel multiplexer/demultiplexer (ISL84052)
and a triple single pole/double throw (SPDT) switch
(ISL84053) designed to operate from a single +2V to +12V
supply or from a
鹵
2V to
鹵
6V supply. All devices have an inhibit
pin to simultaneously open all signal paths.
ON resistance is 60鈩?with a
鹵
5V supply and 125鈩?with a
single +5V supply. Each switch can handle rail to rail analog
signals. The off-leakage current is only 0.1nA at +25
o
C or
5nA at +85
o
C with a 鹵5V supply.
All digital inputs have 0.8V to 2.4V logic thresholds, ensuring
TTL/CMOS logic compatibility when using a single +3.3V
and +5V supply or dual
鹵
5V supplies.
The ISL84051 is a 8 to 1 multiplexer device. The ISL84052 is
a dual 4 to 1 multiplexer device. The ISL84053 is a committed
triple SPDT, which is perfect for use in 2-to-1 multiplexer
applications.
Table 1 summarizes the performance of this family.
