Working Principles

The SN74LVC1G3157YEPR is an analog switch that operates based on the control input (IN) signal. When the control input is low, the switch connects the NO terminal to the common terminal (COM), allowing the signal to pass through. Conversely, when the control input is high, the switch connects the NC terminal to the COM terminal, blocking the signal.
