"Classic" Chips

[bogdant]

PIC16F84, PIC16F876, Atmega16, FT232, MAX232

[fcb]

LM317
LM13700

[PKTKS]

TL431
LM320
TDA1515

if not already above

[Yansi]

LM317
LM13700

if 13700, then it also must be the CA3080

What do you mean "more actual"? How do you get much more classic than 40 year old ICs that are still made?

He/she means “more modern”.

In many languages, the word “actual”* means “current”, “up to date”.

FYI to all the non-native English speakers: in English, “actual” does NOT mean “up to date”, it means “real”.

*e.g. German “aktuell”, French “actuel”, Italian “attuale”, etc.

The brain works in funny ways. With my brazilian eyes, I read the original post with the original intent (actual meaning modern) and thought that james_s also understood it this way, not even considering the completely different meaning in English (and I have been living here for 15+ years and know english for many more). Typical neural network behaviour, where the outcome is the neural connection with the highest weight.

CA3140 and TBA810.

[PKTKS]

CA3161
CA3162

segment decoder and drivers...
LEDs still cause me a very good feeling...

madires and emece67 - you both broke the unwritten rule - no 4000 or 74 series...

LM317
LM13700

So classic it went out of production, and has been 'reissued' apparently.

Anyone remember which IC was discontinued when they lost the drawings/masks?

[Yansi]

Went out of production, so what? Many of the ICs mentioned here are out of production. I don't think that being out of production makes it less classic.

Like with the BF245 JFET. Once was what I'd consider a pretty classic, now you can hardly get BF545, which should've been its SMT direct replacement.

If one would like to talk about really classic integrated circuits, in the full, extended meaning, one should not forget the K2-W opamp.

The 308 is a classic, which lives on as the LT1008, LT1012, and LT1097, and there are also rail-to-rail output versions.  I miss the LM11 which was an improved 308 but the Linear Technology parts are almost as good and have higher precision.

The LM10 lives on as the LT1635.

[CatalinaWOW]

I would interpret "classic" as chips which made a huge impact.  If they did that they are probably still used occasionally just because of inertia, the mass of existing documentation and enormous piles of NOS parts still flooding the market.  There are few, if any, 40+ year old chip designs that are currently the best choice for new designs, though there are several that are adequate in many applications.

Two I would add to the list are the CD4046 PLL chip and maybe the CD4060 14 stage ripple counter w oscillator.

Here is a review:



Hint: It's not rail-rail output.... 

[Zero999]

If we're going to include glassware, then how about the 12AX7?

The LM393/339 have been mentioned, but what about the LM311, which has an output stage capable of up sinking up to 50mA?

[Yansi]

If LM311, then we should add LM319. 

[emece67]

[Circlotron]

If we're going to include glassware, then how about the 12AX7?

And of course 6L6/807, and 6CA7/EL34. In particular, the 6L6 has been in continuous production since July 1936.

[Le_Bassiste]

LM741
CA3080
UAA170/180
XR2206
ICL7106
AD536
TDA2003
TEA0652
CNY17
...
probably easier to list non-popular ICs 

[Alex Eisenhut]

The 6522 VIA. They still make em!

[Yansi]

If 6522, why not 8255 (8251, 8253, .. )?   

[Alex Eisenhut]

Because I didn't grow up with those, so obviously they don't count!

[Yansi]

Well... I did not grow up with 6502 and in our postUSSR country, 6502 was never a thing.   

Here almost all was 8080 clones or Z80 clones.

When engineers at my former job complained about yet another Maxim chip being discontinued after they designed it into a project, I would remark "I can still buy 6L6s".
