The Power Source component family includes the digital power supplies VCC, VDD, VEE, and VSS, as shown above. These are used to connect power to digital components which do not have an explicit power pin on their symbol. They can also be wired directly into a circuit as desired.
If you are unsure of the power supply required for a digital component that has its power pin hidden, double-click on the component and click on the Pins tab. Locate the power supply in the Hidden pins list. Some components, will have more than one power supply (for example, a CMOS 4522BD has both VDD and VSS).
Complete the following steps to change the voltage of a digital power supply:
