ISL84582
FN6213.1
Low-Voltage, Single and Dual Supply,
Differential 4 to 1 Multiplexer
The Intersil ISL84582 device is made of precision,
bidirectional, analog switches configured as a differential 4
channel multiplexer/demultiplexer. It is designed to operate
from a single +2V to +12V supply or from a ±2V to ±6V dual
supplies. The device has an inhibit pin to simultaneously open
all signal paths.
ON resistance of 39Ω with a ±5V supply and 125Ω with a
single +3.3V supply. Each switch can handle rail to rail
analog signals. The off-leakage current is only 0.1nA at
+25°C or 2.5nA at +85°C.
All digital inputs have 0.8V to 2.4V logic thresholds, ensuring
TTL/CMOS logic compatibility when using a single 3.3V or
+5V supply or dual ±5V supplies.
The ISL84582 is a differential 4 to 1 multiplexer device.

Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and V-. One
of these diodes conducts if any analog signal exceeds V+
or V-.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or V-. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or V- and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and V- pins constitutes the analog-signal-
path leakage current. All analog leakage current flows
between each pin and one of the supply terminals, not to the
other switch terminal. This is why both sides of a given
switch can show leakage currents of the same or opposite
polarity. There is no connection between the analog signal
paths and GND.
