Still hanging on to that pig-ignorant belief that a 555 is a "bad"
chip which no one should use because you won't? Even when it's the
perfect candidate for the job?

It isn't a "bad" chip, but very rarely an acceptable candidate for any
job in serious electronics these days. There was a thread about this
here a while back, and the concensus was that most professional
electronic engineers don't seem to be using it any more.


** Funny how they sell over 1 billion examples each year then, isn't it
????

Not at all. Legacy designs, and land occasional egacy designer, like
John Fields, are an entirely sufficient explanation.

Hardly an "occasional" designer, what with designs from, say, 30, or
20, or 10 years ago that are still being manufactured and using up
555's like crazy? Nothing wrong with that, is there? Or legacy
designers like me who know how to use a 555 to its best advantage
for many purposes and have no qualms about using it if it's the
device of choice? Nothing wrong with that either. Especially
since, unlike you, _I'm_ still a working designer. You might also
have noticed that, unlike you, I post actual working designs here
from time to time.
