Logic NOR gates: Understanding NOR Gate Operation

Context: Electronic Circuits.

A logic NOR gate is an integrated circuit (IC) that switches its output pin on (HIGH) if (and only if) both of its input pins are off (LOW). It means that its output pin will switch on only if neither input pin 1 nor input pin 2 are switched on.

A logical ON is referred to as a ‘1’ and a logical OFF is referred to as a ‘0’.

NOR gate operation:

• If input pin 1 is off and input pin 2 is on, the output pin will be off.
• If input pin 2 is off and input pin 1 is on, the output pin will be off.
• If input pin 1 is on and input pin 2 is also on, the output pin will still be off.
• If input pin 1 is off and input pin 2 is off, then the output pin will switch on.
