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.
