An AND gate usually has two inputs. AND tells us that both Input A AND Input B have to be 1 (or ON) in order for the output to be 1. Otherwise the output is 0.

For those just getting their start in digital logic, this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

A recent paper in Nature Communications discusses how to 3D print common logic gates using both macro-scale 3D printing techniques and a much smaller version with microstereolithography.

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 ...
