A LOW (0) output results only if all the \ninputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output \nresults. \n\nA NAND gate is made using transistors and junction diodes. By \nDe Morgan's theorem, a two-input NAND gate's logic may be expressed as AB=A+B, \nmaking a NAND gate equivalent to inverters followed by an OR gate.\n\n**The NAND gate is significant because `any` boolean function can be implemented \nby using a combination of NAND gates. This property is called functional \ncompleteness. It shares this property with the NOR gate.**\n\n## Logic table\n\n| INPUT A | INPUT B | OUTPUT |\n|:---------:|:--------:|:----------:|\n| Low | Low | `High` |\n| `High` | Low | `High` |\n| Low |
