|The 7402 IC package contains four independent
positive logic NOR GATES. Pins 14 and 7 provide power for all four
|[NOR SIMULATION] [NOR TRUTH-TABLE]
|Outputs of one gate can be connected to inputs
of another within the same chip or to another chip as long as they
share the same ground. The figure to the left illustrates a basic
circuit showing how to wire inputs and using LEDs to display outputs.
Use caution when wiring chip and be sure to check which pins are outputs and inputs!
NOR GATE Logic-Rules:
If one or both inputs are HIGH, then the output will be LOW. Otherwise, output will be HIGH
