Boards in 6 GitHub repositories, designed in KiCad, that use the 74LVC573AD by Nexperia (-40℃~+125℃ 1.4ns 1.65V~3.6V 1.7ns 3.4ns 74LVC 8 D Latch Tri-State SOIC-20-300mil Latches ROHS). See how each wires it, with its parts, size, README and files; the 74LVC573AD’s symbol, footprint and pinout are on its own page.

mmosko/Zx50
This is the primary CPU board for the Zx50 8-slot passive backplane system. It hosts the Z80 microprocessor (running at 5 MHz to 10 MHz) and acts as the master controller for the primary bus.
