Low-Voltage, Single and Dual Supply,
Differential 4-to-1 Multiplexer
Features
• Pb-Free (RoHS Compliant)
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.
