Description
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. The ISL84581 has an ON-resistance of 39Ω with a dual ±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 ISL84581 is a single 8-to-1 multiplexer device.
