Boards using the SN74LVC244AN
9 boardsBoards in 8 GitHub repositories, designed in KiCad, that use the SN74LVC244AN by Texas Instruments (-40℃~+125℃ 1.65V~3.6V 2 24mA 24mA 3.9ns@3.3V,50pF 4 40uA 74LVC Tri-State Unidirectional PDIP-20 Buffers, Drivers, Receivers, Transceivers ROHS). See how each wires it, with its parts, size, README and files; the SN74LVC244AN’s symbol, footprint and pinout are on its own page.
