Datasheet jokes.

[David Chamberlain]

Sometimes datasheets have some weird / funny things in them...

No way?!, this should be promoted to page one it seems kind of important.



ANY application, ANYTHING at all... But here are some others just in case the first point was not clear.

[ataradov]

I totally understand. From time to time I have to write documentation like this, and for me personally it is incredibly hard to fill out the standard template.

That's exactly my attitude - it is an oscillator, you know if you need one, and if you need one, you know what you want it for.

[Dubbie]

Yeah, those applications sections of data sheets seem kind of a waste of time to me. By the time you get to reading a data sheet you’re not going to say: “Oh, I could make an Ethernet adapter with this!? Let me pivot wildly to do that instead”

And if you already ARE making an ethernet adapter, it’s not like you are going to go through hundreds of data sheets till you find one that says that it is a good application.

[Whales]

This one is unintentional.

An actual drain. WOM!!!!!

[NiHaoMike]

Many Linear application notes have little cartoons in them.

I had a good laugh at this graph, and then realised it's actually true some times and got sad.

True... but more seriously I think they are kind of coded instructions for sales people to call all their customers who fit under any given banners. 'This part is good for Ethernet adapters, I must let so and so know...'  also they give an insight as to why a given product exists and to what market segment it is targeting.

A bit unrelated, but then there is the Imodium Q36 space modulator...

NS took the whole thing to a rather OTT level with their LM0901A1411090451C "Macropower, low performance, degraded circuit operational amplifier" http://www.magma.ca/~legg/TVS/LM0901A1411090451C_Nat_Semi_'78.PDF

As far as I'm aware, the whole sorry saga was inspired by the classic "Umac 606 Infernal Anode Phantasatron" http://www.tubecollectors.org/archives/606.pdf 
[Edit: The cooling requirements and tap of the 25120 WOM are certainly a homage to it]

A colleague at a previous job had a data sheet for a National Semiconductor “Odor I/O.” I’ve been looking for that online for years, and nothing comes up.

There was also a datasheet which showed how to implement all six filter configurations:

Low pass, high pass, band pass, band rejects, all pass and the no pass.

[jfitter]

Not exactly a datasheet, but this little gem from the opening page of a 1970's user manual for an instrument made in Oz. "Activate the master initialization switch to the SEQEB interface" - ie. switch it ON. (SEQEB was the South East Queensland Electricity Board - the power company).

None shall pass!

This one is decades old, but among my favorites from my pro-audio days.....

Behringer has a whole series of power amplifiers called the I-NUKE. The only question: what manufacturer’s design did their copy to make it?

That's literally the graph I commented on four posts ago.

I have seen a filter graph from the filters manufacturer stating pressure drop for flow rate when the filter is new and when fully blocked. The clean line was the expected curve, the fully blocked line was.... a line starting at the same point and later intersecting the clean curve and passing through it making the blocked filter flow more easily than a clean one which breaks physics...... oh it's ok the filters are only used in life support systems, obviously we don't use their data very extensively.......

That's what happens when the pressure drop gets large enough to punch a hole in the filter media...

I've heard of filters that have a bypass if they get clogged, it's conceivable that a clogged filter could bypass and flow better than a new one, obviously not providing any filtering at that point.
