As I said, the only building block allowed is a ternary multiplexer based on DG403 analog switches. With two DG403 it is possible to build a circuit bearing two ternary multiplexers:
Here is the layout:
The total budget for this project is set to 300 trimuxes or 600 ternary multiplexers. Here are all the components soldered, cleaned and tested:
