s, probably now worth more by weight than anything else on four legs .. I went on Digikey, armed with a data sheet, and there do.

I only buy 1 nF, 10 nF, nF etc.

There was a vast selection, but hobbyists used a small subset, because datasheeh hobby suppliers were easier to del with, datashheet well as the ubiquitous Radio Shack. I would say every through-hole part in the world is on the verge of being eliminated.
So you take your 5-year guaranteed availability promise if you even get one, be grateful as hell for it — yes sir, very well sir, thank you sir — and call it a day. Email required Address never made public.
I appreciate your criticism not because the criticism is correct, but rather it is an accurate observation about the lack of part availability. I sure hope not!.
Not all markets are like this. To provide fail-proof as much as possible! Those people probably bought the kit if it was available.

A Understand the actual requirements for the circuit which is non-trivial for the non-EE B Know what in the datasheet reflects the requirements you have and C Be able to compare apples with oranges; or rather, be able to comprehend all the differences and similarities and interpret vastly different families of devices into different usage cases.
The same thing happened when AD acquired Burr Brown. Unless you want to, that is. BTW, for anyone who has to deal with a 3n, observe every ESD precaution in the planet with that part because they are extremely susceptible.
The second gate also made it easy to control the gain when used as an RF amplifier.
Some FM broadcast band tuners used them, so maybe car radios are a source. It completely fails at about 70MHz.
Now all gone, the average cellphone today has no useful parts. And you can go from e. There are markets where product life expectancy and maintainability are more of concern and this introduces some other dynamics. The most commonly seen alternative NE is probably equally suitable, but a bit more expensive.
Because even today, thirty years after the shuffled off this mortal coil, you can still find people specifying it. Redesigning to remove obsolescent components means going back through FAA certification. That is exactly what I suspected.
Some websites are absolutely woeful, bringing up results that have one word of your search in them, and in no way relate to what you need… eg: Circabipolar transistors also had improved noise figure. They apparently have the capability to run a line for the day to get a few thousand chips and inventory them and put them up for sale.
Thus an association was formed, when you want a quick logic function then 74HC is the modern one to go for. I use HC parts as level translators with mixed 3v3 and 5v logic parts because there a good cheap option and do the job well. The big daddy of dead tree reference was the Thomas Register: Compare that with some power mosfets 40637 seems like if you breathe on them wrong they will expire.

Skyworks do detector diodes that are much better than the old germanium ones. Rochester electronics is one such place that will supply parts albeit expensively until the cows come home.
Inverters are not particularly space constrained.
Hang on, this is Hackaday. Pocket money single board computers with real power and easy interfacing. Just an example off the top of my head, nothing against AD parts in general:
