Boards using the 74LS151PC

38 boards

Boards in 28 GitHub repositories, designed in KiCad, that use the 74LS151PC by onsemi (0℃~+70℃ 12.5ns 4.75V~5.25V 400uA 6mA 74LS 8mA Tri-state output DIP-16 Signal Switches, Multiplexers, Decoders ROHS). See how each wires it, with its parts, size, README and files; the 74LS151PC’s symbol, footprint and pinout are on its own page.
