finding the design dates of various ICs?
« on: October 20, 2013, 12:02:35 pm »
So is anyone else frustrated by how IC companies do not like to say when a product was developed?

Is there some kind of data base?

I suppose if you want to build something and use new parts?

If it's JEDEC part number then the company selling it may not be the company that designed it.

why do you need such info ?
there isno way to find out. even the marking on the dies itself is only the mask datecode... and masks have a finit life as well

I am just interested when the engineers came up with something, when was that part cutting edge.

I don't see why they can't write "linear technology engineers designed this part in 1994 and it went to production 1995"  :-//
I figure that you can follow the advertizements but I wonder why its so cloak and dagger.

The part numbering system at Lineary Technology seems quite sequential. A LT1xxxx is definitely much older then a LTx6xxx part. Some parts get their own design note which is dated. Datasheets usually are also dated.

TI openly writes information like this on the datasheet:
"SLOS075I –NOVEMBER 1979–REVISED APRIL 2009"
But I just love those old unreadable datasheets which were scanned from somewhere.
