You or another list member just might be able to use some of them for something useful dm74ls1551n you know what they are. Tuesday, September 06, 4: 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.

The school had given us tons of IC chips that we never used. 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. I dm74sl151n really friken tired of Laplace transforms, lol. Everything else was analog or datssheet related in the associate degree. The pulse output was working although the voltage level kept changing witch confused me. I had one of those.

I managed to identify about half of them and find data sheets and the other half nothing. Then in the bachelors degree it was all communications stuff from telcom to satellite and network dm74s151n. Ah yes, well spotted that man. Send them to me I. OTOH, give them to students, and dk74ls151n lot will get thrown into the trash when then move out at the end of the year If I remember rightly I had to make to with 2k x 1 I think memory chips, of which I would have needed 32 to give the same amount of storage as one of the above!

I think is 70nS cycle time.

Eventually the aluminum die bond wires could corrode away, but that’s not likely to happen very fast. On Sep 6,at 4: On 6 Sep at Blessed are the Greeks. Someone asked a little while ago about whether chips that old are still viable.

Microcontroller discussion list – Public. I don’t think so. My school didn’t give us a pre-stocked junkbox.

Post by thread:[EE] Mystery IC chips

You may as well list the rest of the part numbers you have. Dayasheet am somewhat of a computer programmer so Microcontrollers seemed the logical place and for one reason or another PICmicro was always the one I knew about even though I never used them before. Went to a private tech college and paid obscene amounts of money as datashret penance for screwing off to much in HS and not being able to get into a regular University. The sawtooth output didn’t produce any output.


My place is about 19 millionth on the right. The clue is in the number – the “64” part is the bit-count in k, so it’s 8k x 8. Justin, anything with 74 in it will be 74 duh series TTL or series. 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.

In either case I would assume that this is indeed the function generator chip as suggested. I’d always believed that powering up old equipment once in a while generates enough heat to dry the components out.

Although after seeing you in a kilt, maybe it’s not a stick I should be ready to duck.
