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 |
