CHAPTER 2 - Logic Gates

AND GATE

• The output of AND logic gate will only be 1 if ALL the input values are 1.

OR GATE

• The output of OR gate will be 1 as long as ONE of the input value is 1.

NOT GATE

• Also called an INVERTER.

• The output is the inverse of the input value.

NAND GATE

• NAND gate is combination of AND and NOT gate.

• The output of AND will be inverted by NOT gate to obtain final output of NAND.

NOR GATE

• NOR gate is the combination of OR and NOT gate.

• The output of OR will be inverted by NOT gate to obtain final output of NOR.

EXOR GATE

• The output of EXOR gate will be 0 if all the inputs are of the same values.

EXNOR GATE

• The output of EXNOR gate will be 1 if all the inputs are of the same value.
