| The 74AC175PC used in the previous versions is no longer in production and no suitable substitute is available. The 74AC175SC SOIC-16 version is still available and the PICTIC II PCB layout file below incorporates the SOIC version as a possible replacement. The schematic and code is the same as the PICTIC II above. | The 74AC175PC used in the previous versions is no longer in production and no suitable substitute is available.
