Definition

1. Noun:
   • A logic gate that produces an output that is the inverse of the output of an AND gate: A NAND gate is a fundamental digital logic component. It outputs a logical "0" (or FALSE) only when all of its inputs are "1" (or TRUE). For all other combinations of inputs, it outputs a "1" (or TRUE). This makes it a universal gate, meaning any other logic function can be constructed using only NAND gates.

Usage Examples

• Noun:
  • The circuit designer used a nand gate to invert the signal from the sensor.
  • A basic nand gate has two inputs and one output.
  • You can build an OR gate by combining several nand gates.

Advanced Usage

• Universal NAND Gate: The property that any Boolean function can be implemented using only NAND gates.

  • Because it is a universal gate, the entire processor was built using only nand gates.

• NAND Gate Symbol: Refers to the standard schematic symbol (a variation of the AND gate symbol with a small circle, or "bubble," at its output) used to represent the gate in circuit diagrams.

  • The nand gate symbol on the diagram indicates the signal will be inverted.

Variants and Related Words

• NAND (Acronym): Stands for "NOT AND," which describes its function.

  • NAND flash memory is named for its use of NAND gate architecture.

• AND gate (Noun): The logic gate whose output a NAND gate inverts.

• Logic gate (Noun): The general category of digital circuit components, which includes the NAND gate.

Synonyms

• NOT-AND gate: A descriptive synonym for a NAND gate.
• Universal gate: A term highlighting its functional completeness, though other gates (like NOR) also share this property.

Related Phrases and Concepts

• NAND operation: Refers to the Boolean logic operation performed by the gate.

  • The NAND operation returns false only if both operands are true.

• Built from NAND gates: A common phrase describing circuit design methodology.

  • This flip-flop is built entirely from NAND gates.
