FN6213.3
Low-Voltage, Single and Dual Supply,
Differential 4-to-1 Multiplexer
The Intersil ISL84582 device is made of precision,
bi-directional, 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 0.02nA at
+25°C or 0.2nA 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.
