Working Principles

The ISL43681IR operates based on the principles of solid-state switching. When an appropriate control signal is applied to the input pins (IN1 to IN4), the corresponding normally open terminal (NO1 to NO4) connects to the common terminal (COM1 or COM2). This allows the passage of analog signals through the switch, facilitating signal routing and multiplexing in electronic circuits.
