Working Principles

The PI5A127UEX is an analog switch that operates by controlling the flow of signals between its input and output terminals. When the control input voltage is within the specified range, the switch is turned on, allowing the signal to pass through from the normally open terminal to the common terminal. Conversely, when the control input voltage is outside the specified range, the switch is turned off, blocking the signal flow.
