What is the output of a NAND gate when both inputs are true?

A NAND gate operates based on a fundamental truth table that defines its output. When analyzing the conditions for the output of a NAND gate, it is important to note that the gate performs a logical operation that is the inverse of an AND gate.

The output of a NAND gate is only false (0) when both of its inputs are true (1). In all other scenarios—whether one or both inputs are false—the output will be true (1). Thus, when both inputs are true, the NAND gate produces an output of false (0).

This characteristic makes the NAND gate widely used in digital circuits, including in the construction of various types of logic configurations and memory elements. Understanding this behavior is crucial for building and analyzing digital systems, since the NAND gate is often desired for its versatility in creating other logic gates through combinations.
