Gate
5-4-050
A device having one output channel and one or more input channels, such that the output channel state is completely determined by the contemporaneous input channel states, except during switching transients.
Note: 1 An and gate is a device in which the output channel is in its one state if and only if each input channel is in a one state.
Note: 2 An exclusive or gate is a device in which the output channel is in a one state if one or the other, but not both, of the input channels is in the one state.
Note: 3 A nand gate, or not and gate, is a device in which the output channel is the logical complement of the and gate.
Note: 4 A nor gate is a device in which the output channel is the logical complement of the or gate.
Note: 5 An or gate is a device in which the output channel is in a one state if any one or more of the input channels is in a one state.
