Working Principles

The ISL43681IRZ 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 switch (COM1 to COM4) connects either the normally open (NO) or normally closed (NC) terminal to the common (COM) terminal. This allows the user to selectively route signals through the desired channel.
