Boards in 2 GitHub repositories, designed in KiCad, that use the SN74LS138N by Texas Instruments (0℃~+70℃ 10mA 3/8 4.75V~5.25V 400uA 41ns@5V,15pF 74LS 8mA Decoder Single Supply DIP-16 Signal Switches, Multiplexers, Decoders ROHS). See how each wires it, with its parts, size, README and files; the SN74LS138N’s symbol, footprint and pinout are on its own page.
