Appearance
Behavior
The NAND gate outputs the result of the NAND operation of the 1-bit signals at the input. The output has the value 0 only if all inputs have the value 1.
Unconnected inputs always have the value 0.

Mnemonics
The logical gates of Antares can illustrate their function with so-called "mnemonics". See the chapter Descriptions and explanations. Below is the mnemonic of the NAND gate.
Pins
- Inputs
-
The 1-bit inputs of the NAND gate. Their number is determined by the attribute "Number of inputs".
- Output
-
The 1-bit output of the NAND gate. Outputs the value of the calculated NAND function.
Attributes
- Orientation
-
The direction in which the output points.
- Number of inputs
-
Determines how many inputs the NAND has. There are 2 to max. 8 inputs available. If the NAND gate is already connected to wires, this attribute cannot be changed.
- Output Name
-
The optional name displayed next to the output. This can be useful when the NAND gate forms the end of a complex combinatorial circuit and the logical expression produced by the NAND gate needs to be specified.
