Re: Odd Hp leds in dip package
But the HDSP 2010 have only 12 pins. I think his are 28 pins, hence the HDSP 2450 suggestion, the closest I could find working off my 1986 catalog.

You and me are thinking alike. Just making sure im not taking away a hard to find part from someone else that desperately needs it. --Devin D.

Re: Odd Hp leds in dip package
Looks like the HDSP-2490: http://www.decadecounter.com/vta/articleview.php?item=9 Datasheet: https://mkmakerspace.co.uk/wp-content/uploads/2017/07/HDSP-2490.pdf These are shift register displays, you clock in column data on a common clock. Similar to the HDSP-2010 and relatives. Quite expensive when new, still very desirable today. Don't let the smoke out :P Thanks, Jonathan On Wed, Nov 21, 2018 at 12:36 PM Curious Marc via cctalk < cctalk@classiccmp.org> wrote: > Try to look up HDSP-2450.

Re: Odd Hp leds in dip package
Try to look up HDSP-2450. These are 5x7 alphanumeric displays with shift register drivers included. Yours might be an earlier version of that, or just a commercial temp version of that (the HDSPs are extended temp -55/85C). Maybe the internal part used in the HP9825 or HP 9830 displays, then later commercially sold as the HDSP 2xxx series. I can scan the HDSP data sheet if you can’t find it online.

The HP5033 is the base part number. They are likely to be 30+ years old, and documentation might be hard to come by. Jon

Odd Hp leds in dip package
Hello. Encountered a couple odd parts in the pile today, not sure if they are anything special. Hp branded dip packages with gold leads. They appear to be leds in 4 grid patterns on the face. Im curious what they are out of, most likely an old hp computer or calculator. Part number on the back is hp5033592-101 i could not find any information online about them. If they are of use to someone with a hp conputer let me know. If not im trying to find a datasheet and use them in a project.
