Re: How inaccurate is a 555 or 7555 REALLY?

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.


** What a load of bovine flatulence.

No case to answer.



The 555 ( and variants) have been and continue to be BY FAR the world's
largest selling IC type ever since it appeared in 1972.


You had maybe better read this:

I've got a copy of Camenzind's book,


** Then you are a complete ASS for not comprehending the significance of
the sales numbers.
