Nand gates are quite a useful gate to have in your digital level project since they are made up by an AND gate and an inverter gate. Because this gate already has 2 gates connected as one, it will possibly reduce the size and the complexity of your circuit a lot and also make it easier to debug your circuit if you some across any errors.
Supply voltage | 4.5V ~ 5.5V |
Min high level input voltage | 2V |
Max low level output voltage | 0.8V |
Delay time | 15ns |
