What is the purpose of a NAND gate?

## 1 Answer

Nand gate has 2 inputs and only 1 output and it is equivalent of an and gate.

The output of a nand gate is high(1) only when anyone or both inputs are low(0).and the output of nand gate is low(0) only when both the inputs are high(1).nand gate is also called as universal gate.
