8-Bit Computer Multiplexer and Demultiplexer
In this post, we’ll take a look at multiplexers and demultiplexers. In my 8-bit computer build, I only used multiplexers, you can see them being used in the clock generation circuits. I will however still cover demultiplexers in this post for the sake of completeness. Multiplexers are used to select one of the multiple inputs and output it to one common output. Demultiplexers do the opposite of that and take in one input and put it out through one of the multiple outputs that was selected. Let’s just take a look at the brief explanations and schematic bellow for a better understanding.
