In hindsight, that probably should have been "motorola,mc74hc595" instead. Recently I read that Motorola invented the 74hc59x for their "new" SPI bus as that time, as the 74164 is not 100% SPI-compatible. Given the limitations of the '164 for SPI, is the same true for '165, and should it be "[...]74[...]597" instead? > The problem this has is then that boards will use this compatible string > even if the parts are not actually the Fairchild version, just to get > the match, when they should be using a generic string. They're all supposed to be "compatible". Personally, I wouldn't object to just "74595", cfr. "ns16550a".
