ISL84582

Low-Voltage, Single and Dual Supply, Differential 4 to 1 Multiplexer

Product Status: Mass Production

OVERVIEW

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.
