Low-Voltage, Single and Dual Supply, 8-to-1 Multiplexer

The Intersil ISL84581 device contains precision,

bidirectional, analog switches configured as an 8-to-1

multiplexer/demultiplexer. It was designed to operate from a

single +2V to +12V single supply or from dual ±2V to ±6V

supplies. The device has an inhibit pin to simultaneously

open all signal paths.

Features

• Fully Specified at 3.3V, 5V, ±5V, and 12V Supplies for 10%

Tolerances

• ON-Resistance (r ) Max, V = ±4.5V . . . . . . . . . . . 50

• ON-Resistance (r ) Max, V = +3V. . . . . . . . . . . . 155

The ISL84581 has an ON-resistance of 39 with a dual ±5V

supply and 125 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.

• Single Supply Operation. . . . . . . . . . . . . . . . . . . +2V to +12V

All digital inputs have 0.8V to 2.4V logic thresholds, ensuring

TTL/CMOS logic compatibility when using a single 3.3V or
