A top view of the NOR Gate with the input sides on the top (A), left (B) and bottom (C). The output (OUT) is on the right

NOR Gate is a redstone logic component added by the Project Red (Integration) mod. It outputs a low signal (0) when one of the enabled input sides receive a high signal (1). 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 NOR Gate can be placed on any side of a block.

When right-clicking the gate with a Screwdriver, it will toggle between various permutations of input configurations where one or two of the inputs are disabled. When only a single input is enabled, the gate acts as a "buffer", which amplified a high signal (1) back to the full redstone signal strength (15).

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.

Truth table

This table is only valid when all three input sides are enabled, denoted here by A, B and C. The input sides are all denoted by IN in the game.

Trivia

• 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.
• In the commonly used CMOS technology for integrated circuits, NOR gates are cheaper to implement than OR gates.
