What is a CD4074?

The subject line says it all. I have four of these RCA
ICs in my parts box, but have been unable to ID them.

Any info would be appreciated.

Thanks,

How dumb are you ?

Has the name Google eluded you all these years ? I take it, that's a
radio ham ID, yet you've never heard of 400 series CMOS that came out -
oh - 40 years ago ?

Before that there was 54/74 series TTL and before that 930 series DTL
logic.

Never met any RTL, except discrete simple implementations.

And this fucking ASD fucked pommy cunthead clearly did not even look.


Shooting the vile puke is too kind.

It's not in my ancient Philips printed 4000 series databook but it's
interesting that these guys claim to have some for sale.

Was it a typo though and he meant CD4047 ?

Why not experiment with one of them by connecting 4K7 pullup resistors
to each of the input and output pins? Then do the same with pulldown
resistors. In this way you'll construct a partial truth table. A pin
which goes low while connected to a pullup resistor, or high while
connected to a pulldown resistor, would be an output. You *may* also
be able to differentiate between inputs and outputs by seeing which
pins "float" when disconnected. I'm assuming the power pins are the
same as for other CD407x parts.

This assumes that it is, in fact, a digital device
and that it doesn't use registers.

I'm still waiting to see a photo of it.

I'm almost willing to bet it's something simple, like reversed digits.
There was the CD4047, a monostable/astable multivibrator. 14pin package,
which of course is one extra bit of information that helps to define
an IC.

Maybe smarter than you? That was the easy bit. Now look for that actual
number. Apart from the vague promises of various brokers who might as well be
the undiscoverable aether, the part doesn't appear to exist. I looked at a
few listings of CMOS logic IC's and that one always draws a blank. Michael
Black's suggestion makes sense, a misread of an existing number.

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
they'll go to the trouble of looking for it.

to go.
