How do you suppose the NSC 74C922/923 manage it without pullups?
I have to admit, I've never given it much thought, but these rather uncommon parts seem to manage just fine. In the very few circumstances under which I've used 'em, they've always worked fine the first time. I've got one that's been working just fine since 1977. RE |
