A NAND gate (short for NOT-AND gate) is a fundamental building block in digital electronics. It is a type of logic gate that produces an output which is false only if all its inputs are true. In other words, the output of a NAND gate is the complement of the output of an AND gate1.
Key Principles
The NAND gate operates based on the following principles:
Inputs and Outputs: It can have two or more inputs and a single output. The output is high (1) if at least one of the inputs is low (0). The output is low (0) only when all inputs are high (1)2.
Boolean Expression: The Boolean expression for a NAND gate with inputs A and B is given by ( Y = \overline{A \cdot B} ), where ( \cdot ) denotes the AND operation and the overline denotes the NOT operation2.
Truth Table: The truth table for a two-input NAND gate is as follows:
| A | B | Y ||---|---|---|| 0 | 0 | 1 || 0 | 1 | 1 || 1 | 0 | 1 || 1 | 1 | 0 |Functional Completeness
