As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 ...

A logic gate is a simple device that takes inputs, performs an operation, and outputs a result. For example, an AND gate turns its output on only if all its inputs are on. An inverter (or NOT gate ...

a NOR gate, and any other logic you can dream up. Mechanical computing is decidedly old school, but not at these scales. Turns out, you can make logic out of almost anything. Even Minesweeper.

Each operator has a standard symbol that can be used when drawing logic gate circuits. In an AND gate, both inputs need to be 1 for the output to be 1.

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
