Explain the NAND Gates - Microprocessor?The NAND GATE is a AND gate with the output inverted. Consequently the outputs of a NAND gate would be the opposites of the outputs of a AND gate. The output is true if input A AND input B are NOT both true: Q = NOT (A AND B) A NAND gate able to have two or more inputs, its output is true if NOT all inputs are true.
The Boolean and symbol expression for a 3-input NAND gate is shown below.The NAND gate will have a high output providing all the inputs are not high. Shown underneath is the truth table for a NAND gate. The simplest way to derive the output for a NAND gate is to invert the output of a AND gate.
