Hell no. I doubt it. But I grant it's not that evil either. I reckon they
just shove any number anyone ever searches for on their sites into their
wretched lists to get them higher up the Google rankings...

Has it really NEVER occured to you that those guys are full enough of
shit
that they'd fill in gaps in apparent sequences just to make it look like
they
have everything? No wonder counterfeiters and shysters can profit so
easily
when that kind of gullibility persists.


** For once, the homeless fruit cake is right.

Counterfeiters would not hesitate to sell semis to order with part numbers
printed on them that simply DO NOT EXIST.

What possible complaint about quality or performance could be maintained
after that ??

LOL !!!!



One indication of that is that the sequence numbers are filled in, but
not the package suffixes. Probably it's not so evil as
counterfeiting-- simply that if they get a request for something

It is useful to put the part number in a search engine, but increasingly

what you get is hits from those pages. In the old days, if the only
result was a commercial page, there usually was a one line description
of the device. I know I gathered information that way, often enough of
a clue to find proper information in some other way.

But now, you end up with those pages, and they say nothing about the
device. And after that, it really doesn't matter whether they are faking
it or not, since the webpages provide no useful information.

It's odd how things have changed in 13 years. Back then, people had
their old databooks and would use those to look up devices when people
would ask questions. They are still a fairly definitive source, since
they exist from the time of those devices, while anything in electronic
form requires that someone took the effort to convert "stale" information
into electronic form. The more obscure and the older the device, the less
likely that's going to happen. So the databooks are still useful.

There were a few numbers in the original RCA 'A' series that were
dropped early on because no one seemed to want them. I can't find my
original RCA COSMOS Databook right now to see what they were. RCA may
have assigned numbers for parts that were only shipped as samples, as
well.

I must confess that had never occurred to me, but now that you've
suggested it, I've confirmed that other non-existent (?) parts also
show up in the listings, eg CD4091, CD4092, HEF4074, CD4083, CD4084,
CD4088. However, all except the last example could be accounted for by
typos in the last two digits.

The gap in the CD407x sequence (and others) begs the question, how are
part numbers chosen and why was 4074 not used? Are certain numbers
reserved? Do they reflect prototypes that never made it into
production?

CD4037 would probably be an example of one of those. It's at least
real. (Triple AND-OR Bi-Phase pairs). Just the thing for your plated

I will see if I can find the original RCA book when I'm feeling
better, to see if any of those missing numbers existed. Not many people
had, or kept the early books. I know I ditched most of my early to mid
'60s books, or gave them away when I found newer editions. Too many
parts were NLA by 1970, so I didn't see any reason to keep them. The
only reason I kept the RCA book was I had to pay for it while I was in
the Army.

Wow, what interesting responses! With the request that I post a picture
of the part, I tried to located them - with no success. I then went over
my old parts invoices to determine when I had purchased them. It turns
out that I had bought parts from a defunct Pennsylvania research company
in 1998.

The part was described as "SCL4074BE by SSI", with four pieces
available. However, the shipping invoice showed that this item wasn't
shipped, and a $0.60 deduction was made. It seems I updated my parts
list without doing a proper inventory.

Normally I would apologize for wasting peoples time with this question,
but given the snarky answers, I won't -:)

Ask them if you want their answer. Not that it's likely to help you. Work it
out yourself. Ok, I'll spell it out for you. They see a range with apparent
gaps. They don't know if the missing numbers mean real parts or not, so they
fill the gaps in so their listings have a higher chance of returning as
Google results. Obviously if the part doesn't exist then it's less likely to
get called for, but they don't kmnow that, do they? Easier for them to add it
to the list and be done with it. Especially if it appears via one of theor
own search tools as the result of a typo. Again, they don't know what's real
all the time, they just add anything that looks like it should be added. Just
LOOK at one of their wretched lists some time, that alone should convince you
of this. All numbers and no data.

Don't ask! Ultimately you'll be told what someone thinks you want to hear.
That's why those shysters exist, they know there are always people who do
this. If you really want to know, look for the details. Once you find a
detailed description, maybe even a data sheet, and perhaps even a second
primary (manufacturing) source of such data, then you can assume it exists
After all, it works for damn near all parts that do. If someone with lots of
numbers and no data offeres you stuff as rare as hen's teeth, don't touch
them with a ten foot pole. No beanstalk is EVER going to grow from those
beans.
