Understanding Logic Gates

NOT gate

The NOT gate takes the input and produce the invert of that input on its output.

	Input A	Output Z
	1	0
	0	1

AND gate

The AND gate takes in two inputs. When both input A AND input B are high the output will be active.

	Input A	Input B	Output Z
	0	0	0
	1	0	0
	0	1	0
	1	1	1

NAND gate

The NAND gate takes in two inputs. When both input A AND input B are high the output will NOT be active.

	Input A	Input B	Output Z
	0	0	1
	0	1	1
	1	0	1
	1	1	0

OR gate

The OR gate takes in two inputs. When either input A OR input B are high the output will be active.

	Input A	Input B	Output Z
	0	0	0
	0	1	1
	1	0	1
	1	1	1

NOR gate

The NOR gate takes in two inputs. When either input A OR input B are high the output will NOT be active.

	Input A	Input B	Output Z
	0	0	1
	0	1	0
	1	0	0
	1	1	0
