Use this as reference for some of the basic gates: Logic Gate Symbols

Contents 1 AND 2 OR 3 XOR 4 NOT 5 NAND 6 NOR 7 XNOR

[edit] AND

This only outputs high when all inputs are high.

[edit] OR

This outputs high when any of the inputs are high.

[edit] XOR

This outputs high only if ALL of the inputs are different (for binary applications, only 2-inputs are possible).

[edit] NOT

This inverts the input. If input is high, output is low, and vice-versa.

By applying this logic to the previous gates, we can come up with a few more:

[edit] NAND

This outputs the opposite of an AND gate, which means that the output is high if the inputs are anything but all on.

[edit] NOR

This is the opposite the OR gate, which means the output is high only if all inputs are low.

[edit] XNOR

This is the opposite of the XOR gate, which means the output is high only if all inputs are the same.
