Well to be honest the HW people did and it's all I could test with. I don't know much about these naming schemes, apart from the intuition it has to do with frequency and line levels. > Ideally, you want to put the oldest "manuf,74x594" variant here. What do you mean by oldest? What would you suggest? it's funny because the chip is going to be used on a new product that is meant to be produced for years. > I once read it was Motorola who invented the 7459x parts, to interface with > SPI. > > Gr{oetje,eeting}s, > > Geert > Thanks for your comments!
