The output of this port is active or '1' When the input is '1'. A buffer is used for driving many inputs. In boolean logic: Q = A Truth-table: A | Q -----|---- 0 | 0 1 | 1 0 = inactive = GND = 0V = OFF (Wires are green when inactive) 1 = active = Vcc = 5V = ON (Wires are red when active) You can drag this component to another position by clicking inside the body of the port, hold the mouse button, move to the new position, and release the mouse button.
