The Intersil ISL43841 device is a precision, bidirectional, analog switches configured as a a dual 4 channel multiplexer/ demultiplexer designed to operate from a single +2V to +12V supply or from a ±2V to ±6V supply. The device has a latch bar pin to lock in the last switch address. ON resistance of 39Ω with a ±5V supply and 125Ω with a +3. 3V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 0. 1nA at +25°C or 2. 5nA 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.
