VCC | 14 | Power | Supply Voltage |
GND | 7 | Power | Ground |
A1 to A3 | 1, 2, 13 | Input | Inputs A of the three NAND gates |
B1 to B3 | 3, 4, 5 | Input | Inputs B of the three NAND gates |
C1 to C3 | 9, 10, 11 | Input | Inputs C of the three NAND gates |
Q1 to Q3 | 12, 6, 8 | Output | Outputs from the three NAND gates |
A NAND gate is a logic gate that works like an AND gate with a NOT gate on the output.
A 3-input AND will only be high when all the inputs are HIGH. This means that a 3-input NAND will only be LOW when all three inputs are HIGH.
