Working Principles

The DG442ETE+ is an analog switch that operates by controlling the flow of signals between its input and output terminals. When the control logic is activated, the switch connects the input terminal (IN1 or IN2) to either the normally open (NO) or normally closed (NC) terminal, depending on the desired signal routing. This allows for efficient switching of signals in various electronic circuits.
