01
Choose a Logic Gate Simulator gate
Start with AND, OR, or NOT, then compare NAND, NOR, XOR, and XNOR. Keep the selected gate visible while you change the inputs.
- Use 0 and 1 as LOW and HIGH
- Start with one gate before chaining

Logic Gate Simulator interactive logic tool
Start Logic Gate Simulator here: choose a gate, toggle A and B between 0 and 1, inspect the highlighted truth table row, then drag gates into a simple circuit chain.
Logic Gate Simulator mode
Use one gate for a clean truth table, or switch to the circuit builder for chained gates.
Binary inputs
Click each input to switch between 0 and 1. NOT uses input A only.

Real-world logic gate uses
AND
Multiple conditions must be true at the same time, such as an enable signal and a safety check.
OR
Any one condition can trigger an action, such as either button starting an alert.
NOT
A signal is inverted, such as turning an active-high signal into active-low logic.
XOR
Two inputs are compared to detect whether they are different, which is useful in adders and parity checks.
