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:

Also original TRIMUX is available on Tindie in form of PCB, KIT or pre-assembled:

Note: original TRIMUX has wider space between groups of pins than SMD version described above!

This is a link to original TRIMUX on DG403 :)

I think original drawing is more clearly explaining what is going on over there:

May be I should redraw it to have TERNARY UNIVERSAL UNARY ELEMENT (or "ternary selector") on both sides to match TRIMUX schematics exactly ;)
