Working Principles

The DG442DY-T operates based on the principle of field-effect transistors (FETs). It utilizes MOSFET technology to control the flow of signals. When a control voltage is applied, the corresponding switch turns on, allowing the signal to pass through. The break-before-make switching action ensures that there is no short-circuiting during the transition between different signal paths.
