Working Principles

The DG418CY+T is an analog switch that operates based on the principle of MOSFET transistors. It utilizes a combination of p-channel and n-channel MOSFETs to create a bidirectional switch. When the enable control signal is active, the switch connects the input terminal to the corresponding output terminal. Conversely, when the enable control signal is inactive, the switch disconnects the input and output terminals.
