The pulse output was working although the voltage level kept changing witch confused me. Lots of the chips I cant ID don’t have manufacturers and just half half washed off numbers printed sloppy and crocked across them but a few are from big name manufacturers.

Also I’ve seen discolouration on pins where they enter the IC body and I wonder if this is some sort of material migration or break- down at the seal. I don’t think so. Pay no attention to the man behind the curtain! On Tue, dm74ls151h Sep Eventually the aluminum die bond wires could corrode away, but that’s not dtasheet to happen very fast.

In either case I would assume that this is indeed the function generator chip as suggested.

I can defiantly come up with some use for them if anyone can ID them I like having a large surplus of components Its just It seemed pointless to keep them around not knowing what they were. Bill Original Message From: Jinx, On Wed, 07 Sep OTOH, give them to students, and a lot will get thrown into the trash when then move out at the end of the year I have little knowledge of the Motorola variety preferred the Commodore enhanced version but I believe they were used extensively in bygone days in small micro-computers before PCs became popular http: A lot of that stuff gets donated and slowly sits around becoming obsolete until the department moves and decides to throw it out.

Stuck eight of thoses ‘s on my Kim in order to get some real computting power. I managed to identify about half of them and find data sheets and the other half nothing.

Now I put this together quickly on a breadboard with approximate value components so I didn’t expect much and if I had any sawtooth output I would of considered it a success.

Hard to imagine how small memory was back then.

I’d always believed that powering up old equipment once in a while generates enough heat to dry the components out. They’re supposed to be hermetically sealed but I do wonder about ingress of moisture. I put together the pulse generator circuit in that datasheet. You or another list member just might be able to use some of them for something useful once you know what they are.

I doubt anything too useful will show up in these. As far as the school giving us a junk box of parts I dm74lss151n sure I paid at least twice what I could of put it together myself for. I am really friken tired of Laplace transforms, lol. Maybe it’s something else that is going on. On Sep 6,at 4: So now I figure I want to get some projects and practical experience under my belt before I move on for a Masters and yet more calculus and theory.

When I get home tonight I will list the rest Justin.

When I was searching for myself I really fatasheet on finding a quite literal match as I really don’t know the logic behind the numbering. The sawtooth output didn’t produce any output. To fit into their part number system and those numbers it would be something like Dm74,s151n, which doesn’t seem to be a valid part number.

Send them to me I will recycle them in an environmentally-friendly manner! Someone asked a little while ago about whether chips that old are still viable. Dave, On Mon, 5 Sep Although after seeing you in a kilt, maybe it’s not a stick I daasheet be ready to duck.

The school had given us tons of IC chips that we never used. You would think that they would keep data sheets available for them even if they are no longer in production. Blessed are the Greeks.
