NOT Gate is a redstone logic component added by the Project Red (Integration) mod. It acts as a signal inverter used in electronics, also referred to as NOT Gate. When receiving a high signal (1), it will output a low signal and when it receives a low signal (0) it will output a high signal. This is very similar to a basic inverter made using a block and a Redstone Torch. Any redstone signal strength that is not zero is accepted as a valid high input signal (1). A high output signal from the gate is always a redstone signal at maximum signal strength (15).

Like all logic blocks added by the mod, the NOT Gate can be placed on any side of a block. This, with the addition of the fact that it is a single block, makes it a lot more compact and versatile than a vanilla inverter circuit.

When right-clicking the gate with a Screwdriver, it will toggle between various permutations of output configurations where one or two of the outputs are disabled. This means they will not output a signal when the input is low (0) and they will not connect up to any wires.

It takes two ticks for a signal change to propagate from the input to the output of the gate. This means that as there are 20 ticks in a second, it would take one second for a signal change to propagate through ten of these gates.

When the player hovers over the block with their crosshairs, a layout is drawn around the block denoting the names of the in-/output sides.

NOT Gate (Project Red) has no known uses in crafting.


  • In real integrated circuits using technologies such as NMOS or CMOS transistors, a gate will output the current from the power source, which means that a high signal output does not rely on the voltage of the signal that was input, as these signals degrade when they are fed into many components. By this means, a high signal is always amplified to full strength when it exits a gate component.
