Logic Gates

2
AND Function Output Y is TRUE if inputs A AND B are TRUE, else it is FALSE. Logic Symbol Text Description Truth Table Boolean Expression AND A B Y Y = A x B = A B = AB AND Symbol

3
OR Function Output Y is TRUE if input A OR B is TRUE, else it is FALSE. Logic Symbol Text Description Truth Table Boolean Expression Y = A + B OR Symbol A B Y OR

4
NOT Function (inverter) Output Y is TRUE if input A is FALSE, else it is FALSE. Y is the inverse of A. Logic Symbol Text Description Truth Table Boolean Expression AY NOT NOT Bar Y = A Alternative Notation Y = !A

5
NAND Function Output Y is FALSE if inputs A AND B are TRUE, else it is TRUE. Logic Symbol Text Description Truth Table Boolean Expression A B Y NAND A bubble is an inverter This is an AND Gate with an inverted output Y = A x B = AB

6
NOR Function Output Y is FALSE if input A OR B is TRUE, else it is TRUE. Logic Symbol Text Description Truth Table Boolean Expression Y = A + B A B Y NOR A bubble is an inverter. This is an OR Gate with its output inverted.
