Does National answer to technical requests?

I asked them a question two weeks ago, and I haven't got any type of feedback yet. The first time I used the web form, then when I didn't get any kind of feedback (not even the e-mail notification "we received your inquiry and will answer soon" like every other company does), I also tried the european e-mail address ( snipped-for-privacy@nsc.com). No answers whatsoever. I've used the technical support of almost all the semiconductor companies, and there is indeed a wide spectrum of service level, from the fastest and more thorough (e.g. Texas Instruments) to the slowest and less thorough (e.g. Freescale), but in all cases I always got an answer. Until now.

National Semi support is rather bad. In the 70s and early 80s, NS support was great. Now days, you need to call them via telephone to get any support.

... or know a person there and his/her email address. When I have a question about a switcher I write directly, not via some support form.

Haven't had the opportunity to need National support for about a year now. The last time I needed them it was also regarding one of their switcher products. I recall using the online form and they responded rather quickly (a couple days).

So, it could depend on the product line in question. Just a guess, though. (I'm in the US, if you think that's relevant to your situation.) Good luck!

Un bel giorno mpm digitò:

In my case it's a comparator, the LPV7215. I need to know the maximum current of its input clamp diodes, but this parameter isn't indicated in the maximum ratings. This parameter changes a lot from manufacturer to manufacturer and also from part to part; I've seen values from below 1 mA to tens of mA, so I don't think it's wise to just take a guess.

The funny thing is that the datasheet actually dedicates a whole paragraph to the clamp diodes and on how you can protect the device from high voltages by putting a "large resistor" (sic) in series with the inputs. :)
