This is a four to one multiplexer (4x1 MUX.) This device accepts four bits as input and uses two one-bit selectors to choose one for the output. Useful for building a computer in Minecraft, or just having a convenient system for choosing different bits. Search online for tutorials on how to string multiple MUXs together to form even bigger ones!


NOTE: As per convention, the MUX is enabled when the enable pin is off and is disabled when the enable pin is on.
