AND Gate
The two-input AND gate implements Boolean conjunction: its output is HIGH only when both sampled inputs are HIGH. Use it to combine simultaneous logic conditions.
Overview
The two-input AND gate implements Boolean conjunction. Its output is HIGH only when both sampled inputs are HIGH.
DigiSim Interface
| Direction | Pins | Behavior |
|---|---|---|
| Input | A, B | Two one-bit operands. |
| Output | Y | Driven Boolean result. |
Truth Table
Y = A · B. A defined LOW determines the result even when the other input is X; otherwise a
relevant driven unknown produces X. A released Z input follows Logic Lab's LOW sampling
convention.
Simulation Boundary
This gate is a functional Boolean component. It does not specify an IC family, transistor network, supply voltage, output drive, fan-out, or physical propagation characteristics.

Frequently Asked Questions
What is an AND gate?
An AND gate is a basic logic gate that outputs 1 (HIGH) only when all its inputs are 1. If any input is 0, the output is 0.
What is the truth table of an AND gate?
For a 2-input AND gate: 0 AND 0 = 0, 0 AND 1 = 0, 1 AND 0 = 0, 1 AND 1 = 1. The output is HIGH only when both inputs are HIGH.
What are practical applications of AND gates?
AND gates are used in enable circuits, address decoding, multiplexers, and any circuit where multiple conditions must be true simultaneously.
