Working Principles

The 74LVC1G3157DRYRG4 is an analog switch that operates based on the control signal applied to the IN pin. When the control signal is low, the switch connects the NC pin to the common terminal, providing a closed circuit. Conversely, when the control signal is high, the switch connects the NO pin to the common terminal, creating an open circuit. This functionality allows the IC to route signals between two different paths.
