NOT Gate

The one-input NOT gate implements Boolean complementation, driving HIGH for a sampled LOW input and LOW for a sampled HIGH input.

Overview

The NOT gate, or inverter, implements Boolean complementation.

DigiSim Interface

Direction Pin Behavior
Input A One-bit operand.
Output Y Driven complement of the sampled input.

Truth Table

Y = ¬A. A driven unknown input produces driven X. A released Z input follows Logic Lab's LOW sampling convention and therefore produces HIGH.

Simulation Boundary

The component does not model a physical inverter's transistor arrangement, voltage transfer curve, noise margin, current, loading, or propagation limits.

Frequently Asked Questions

What is a NOT gate?

A NOT gate (inverter) has one input and one output. It produces the opposite output to its input: 0 becomes 1 and 1 becomes 0.

Why are NOT gates important?

NOT gates are essential for implementing Boolean algebra, creating NAND/NOR gates from AND/OR, and building flip-flops and other sequential circuits.
