I am pretty new to circuit/PCB design and have noticed something that confuses me. Let's take a logic gate as an example.
In my circuit design software, the schematic symbol for a logic gate has 3 pins: A, B, and Y. But when I look at the datasheet, I see that the actual component has 5 pins: A, B, Y, Vcc, and GND.
Why wouldn't Vcc and GND be included in the schematic? Do I only add those connections once I transfer my schematic to a PCB?
