ISL84582

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 39

Ω 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

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.

Table 1 summarizes the performance of this part.
