How it works

Each input turns off the torch on its own block; the dust between the torches is off only when both are; a third torch under that dust reads it: lit only when both inputs are on.

  1. The input stages and final inversion combine the two controls.
  2. The output becomes on only after both inputs are on and the circuit settles.

Truth table

Settled outputs after the inputs stop changing. 1 is on, 0 is off. Every row is checked in the simulator in all four rotations.

Inputs and outputs

  • InputA (x 0, y 0, z 0)
  • InputB (x 0, y 0, z 2)
  • OutputA and B (x 5, y 0, z 1)

Blocks you need

4 × redstone dust, 3 × stone, 2 × lever, 2 × redstone torch, 1 × redstone torch (on a wall), 1 × redstone lamp.

Build it in the game: 13 commands

Relative to where you stand, with x running east and z running south. Paste one line at a time into chat, or into a chain of command blocks. The block art is the game's own; the layout is what the page above shows.
