NAND gate

The NAND gate is a redstone circuit added by RedLogic. It is a logic gate for complex redstone circuits. It emits a redstone signal on the output side until all input sides receive a redstone signal (see Usage).

The circuit would be possible with Vanilla redstone mechanics, but this block reduces the size of the circuit to 1 block. This makes complex circuits clearer and easier to control. In electronics, this gate enables the physical execution of the boolean function "NAND (negated AND)".

Usage
The NAND gate has three input sides and one output side for redstone devices. Using the Screwdriver from RedLogic, the orientation of the gate can be changed freely in all four directions. Furthermore, using the screwdriver while crouching, the input sides can be turned off and on again in various combinations.

As long as not all input sides receive a redstone signal, then a redstone signal is emitted on the output side. If redstone signals reaches all input sides of the gate, then the redstone signal on the output side is terminated.
