How it works
This is a basic analog switch. When the control input is high, the X and Y analog inputs are connected. When the control input is low, they are not connected.
How to test
Connect X to digital high. Connect a pull-down resistor from Y to ground.
Change the value of the control input. Verify that the inverse of the control input is correct. Verify that the voltage at Y matches.
