My understanding of how integrated circuits work is a little cloudy. Obviously, an IC has many pins, in this example, I will use a quad 2 input AND gate, pins 1 and 2 will be inputs for the first AND gate, and 3 will be the output for the first AND gate.
What I don't understand is the GND and VCC pins. GND is obviously ground and all circuits must return to ground to complete the circuit, VCC is the voltage source .
Looking at the diagram, it's not clear how the 4 AND gates are powered, none of them seem to have a connection to VCC nor GND. Do all these AND gates have an implicit connection to VCC and GND? and it's just not shown in these IC diagrams?
