Description

The Intersil ISL43681 and ISL43741 devices are precision, bidirectional, analog switches configured as an 8 channel and a differential 4 channel multiplexer/demultiplexer. They are designed to operate from a single +2V to +12V supply or from a 2V to 6V supplies. The devices have an inhibit and inhibit bar pin to simultaneously open all signal paths. The devices also have a latch bar pin to lock in the last switch address. ON resistance of 39 with a 5V supply and 125 with a +3.3V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 0.1nA at +25oC or 2.5nA at +85C. 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 ISL43681 is a single 8 to 1 multiplexer device and the ISL43741 is a diff 4 to 1 multiplexer device.
