FN6213.1
Low-Voltage, Single and Dual Supply,
Differential 4 to 1 Multiplexer
Features
• Pb-Free Plus Anneal Available (RoHS Compliant)
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.
• Fully Specified at 3.3V, 5V, ±5V, and 12V Supplies for 10%
