What do you want? With such a small number of pins there are only a finite number of permutations.  >:D 8)

I think he's referring to the "transparent top view" designation of the SOT1061 package. That is slightly perverse.  :P

Well, it's two things. The inconsistency of the mechanical representation (one labelled transparent top view, the other suggesting top view by the dotted lines, the other one... I don't know? Guess which one it is? Know from previous experience it's probably top view and hope for the best?) The other things is the randomisation of the pinning. That's just bad. And awaiting havoc somewhere down the line in some CAD library.

The SOT223 is TOP view, the SOT89 is BOTTOM view - in both cases it's convention to have the collector on the tab and centre pin on those packages. When those packages are used for regulators the tab and centre pin are normally the output.
--- End quote ---
Nope, the SOT223 and SOT89 are both top view and BCE from left to right; the actual pinout is the same and correct to the conventions you just described.

Just for some perverse reason, in that diagram they reversed the numbering AND the pin order on the SOT89, so the pinout actually doesn't change. I've seen similar before often enough that sadly, it didn't even ping my RADAR this time; I only noticed the new & different perversity of the SOT1061. :-//

Then it depends on the resiliency of the local cell net.   Our broadband lastmile provider (which is opto transmission) has about 2h UPS on their active gear. This, sadly enough, has been verified by yours truly.

Edit: I've looked at the genset that powers the cell site we have about 500m from home. There are preparations being enforced and somewhat financed by the regulator.

Probably still better than GorillaServers' DataCenter.  :-DD

It's a good genset, not a cheapo. Providing there's funding and incentive, we're pretty good at building resilient telecoms here.
--- End quote ---
So no incendiary failover protocols built-in then...?  :-DD

@Zucca your poster was way incomplete. The entire Bell labs unix line was left out ...

There was also no mention of IBM's OS/2  >:D >:D >:D

And was a damn good O/S that Itty Bitty Morons fumbled. By the time it was perfected and actively marketed MS was in firm control.

I was OS/2 Warped as a youth.  >:D

and I may have kept a wee tetch o' the Warped as an adult...  :-DD

Yep, minimum one hour bagel-imposed downtime right there.

Please at least get the quotes correct. Too much trouble ? Then delete the post and try again.

I have a friend who once went through the "open" MS Office file format specification when it was released. He found such gems like:

"The handling of this function shall be as it was in Word 6."  Full stop. No explanation. In the released documentation. No surprise then that Word is as buggy and inconsistent as it is..
