I've been laid up for a while with a dislocated knee, (my 70th birthday present, I don't like this "growing old")
What I am looking for is a comprehensive list of logic i.c functional equivalents, i.e a 4024 is the same function as a 74HC4024, but i'm having trouble comparing SN74******** with say motorola's i.c's. I don't mean just direct replacements, although that would be handy, and am not concerned so much with the different classes of evolution, such as interfacing, working voltages etc.
Trolling through manufacturers data sheets to find for instance, different Hex inverters, or divide by 10 BCD up-down counters, is laborious to say the least, and so many are now obsolete and data unavailable.
Now I know that many would say "why bother" but I run a small club where most of the members are disadvantaged in one way of another and find electronics therapeutic. In the last few months, we have been lucky enough to have received donations of components from several sources which include many dozens of logic i.c's from different series.
There is no need for the latest processor controlled designs, just as much fun is had by them building circuits found in older publications.
My career in electronics was mostly spent in analogue and R.F design and latterly servicing of consumer electronics. I did not become as well versed in all the logic i.c family's as I would have liked so any help would be appreciated.
