Well, so much for the old maxim...

That saying come from people who would now & then buy some
standard parts. When you let them do custom chips, like our
former fiber optic company in Berlin with a > 300 people
pilot pre-production line and mass production in the east,
then you felt besieged by their busy salesdroids.

Let\'s hope that AD handles that as good as the Hittite
aquisition.

Standard products were never really important for them.
Funny enough, I have some LT1028 from Maxim that I got
from their local representative. Methinks they never
made it into their standard portfolio, although they
were OK, AFAICT.

I got the impression that Maxim was more interested in high-volume
custom business than selling to ordinary customers. And that when a
giant customer stopped buying, they dumped the parts and the small
customers. That happened to us twice.

TI seems to keep parts available forever. They will still sell you an
SN7400N.




Maxim are the only source of really good/fast comparators, have been
that for almost 30 years now. I have used a DAC of theirs which has
been available via the normal distributors for 20+ years.
ADI have been very good maintaining product availability, I can still
buy unique opamps of theirs I have first designed in around 1990.
Apart from the general bad feeling about mergers merging all into
one which seems to be the way things are going I would not mind
this particular one.

We designed the MAX9690 fast comparator in to the NIF timing system.
After some months of use, they all began to fail. MAXIM discontinued
it without notice. We had to replace about 3000 comparators with
little baby boards.

ADI has really good comparators, the ADCMP series. ADCMP582 has 180 ps
prop delay and 37 ps output edges.

Maxim hurt us on their FLECAP and Dallas delay lines, too.

Is it a good idea for designers to have their buyer occasionally check all
their important vendors for \"last time buys\" of parts? Not just parts in
active production, but also parts for potential use and those \"favorites\".

There are services that do that. You send them your inventory list and
a monthly fee, and they alert you to EOL issues. It makes sense to
centralize that function.
