			The '''74x00''' (and its military grade equivalent '''54x00''') is a Quad 2-Input [[NAND gate]] and one of the most important components in digital electronics. The chip provides four groups of 2 inputs (labelled '''A''' and '''B''') and a single output (labelled '''Y''') which outputs a HIGH (1) signal when either or both inputs are LOW (0), otherwise when both inputs are HIGH, the output becomes LOW.
