Boards in 2 GitHub repositories, designed in KiCad, that use the CH446X by WCH (Nanjing Qinheng Microelectronics) (-40℃~+85℃ -7V~5V、4V~12V 10pF 12ns 24:1 45Ω 5 50MHz LQFP-44(10x10) Analog Switches, Multiplexers ROHS). See how each wires it, with its parts, size, README and files; the CH446X’s symbol, footprint and pinout are on its own page.
