Boards using the 74HC14D
7 boardsBoards in 7 GitHub repositories, designed in KiCad, that use the 74HC14D by Nexperia (-40℃~+125℃ 1 1.5V~4.2V 21ns@6V,50pF 2V~6V 2uA 300mV~1.2V 5.2mA 5.2mA 6 74HC Schmitt trigger SOIC-14 Inverters ROHS). See how each wires it, with its parts, size, README and files; the 74HC14D’s symbol, footprint and pinout are on its own page.
