When you use these for communications, you need a synchronized clock at each end so that you apply first a 0 to both Select inputs to transfer the data on one input to the corresponding output and then a 1 to transfer the data on the other side.

So if your data rate on each line is, say, 100 bits per second, the data rate on the single line connecting them would be 200 bits per second with half of it being from one line and half from the other.

If you have a 16 input mux and demux, the data rate on the connecting line would be 16 times the data rate on the individual lines.
