Hello,
thanks for answer

i know MUX,
 i use chip 74LS157

 i read a lot on internet for DEMUX, like i understand is D input(wich must be ON) and S line
and Output, the result depends on Input of S lines

but can you please tell me, what to USE how to build the circuits(because i have no information and also
i am a beginner i watch the videos of Ben Eater, after i learn Nand2Tetris)
