NAND gates:
- This gate is the combination of AND and NOT gate.
- It performs an inverse of AND gate.
- NAND gates are used for detecting if a single input to a digital system has gone low.
- It is only going to logic low and has an output that is normally at the logic high.
The diagram of the NAND gate is given below:
