OTOH, give them to students, and a lot will get thrown into the trash when then move out at the end of the year Then in the bachelors degree it was all communications stuff from telcom to satellite and network protocols. Dave, On Dm74s151n, 5 Sep Send them to me I. Better than just chucking them out. The clue is in the number – the “64” part is the bit-count in k, so it’s 8k x 8. The sawtooth output didn’t produce any output.
To fit into their part number system and those numbers it would be something like NJMJ, which doesn’t seem to be a valid part number.
My place is about 19 millionth on the right. I can defiantly come up with some use datasyeet 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. Yea; I’m not home right now but I was thinking the same thing quite frankly after having little luck with google I didn’t expect for as many responses so quick. Most of witch were odd brands that are out of business now that they probably got for next to nothing.
It’s Allegro anyway You shouldn’t have too much trouble finding datasheets for these.

You may as well list the rest of the part numbers you have. Stuck eight of thoses ‘s on my Kim in order to get some real computting power. Eventually the aluminum die bond wires could corrode away, but that’s not likely to happen very fast. I am really friken tired of Laplace transforms, lol. Pay no attention to the man behind the curtain! Ah yes, well spotted that man. A lot of that stuff gets donated and slowly sits around becoming obsolete until the department moves and decides to throw it out.
I doubt anything too useful will show up in these. Best regards, Spehro Pefhany –“it’s the network I put together the pulse generator circuit in that datasheet. I don’t think I recognize that appearance. Anyway, I don’t think there’s any reason to expect a chip made in ’77 is going to be unreliable in ’05 unless and this is a big ‘unless’ the leads are in such condition that you can’t get a reliable solder joint.

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: 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!
The way it was set up was I got an associate degree first then reapplied for the BS it wasn’t something you could sign up for right from the start. You would think that they would keep data sheets available for them even if they are no longer in production.
Microcontroller discussion list – Public. I think is 70nS cycle time. If any of these are particularly static sensitive they probably are keeshed datasyeet 4 years of floating around in a tackle box in the trunk of a car and dozens of hands digging through them looking for specific parts in labs.

Many of the chips made back then are not useful because there are much better faster, lower power, higher capacity, etc. 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 pulse output was working although the voltage level kept changing witch confused me. Jinx, On Wed, 07 Sep On Tue, 06 Sep I don’t think so. But that doesn’t stop my “good chip to keep” detector from going off. When I was searching for myself I really depended on finding a quite literal match as I really don’t know the logic behind the numbering.
On Sep 6,at 4: Lord knows why the school gave us some of this stuff though or where they got there stock from. I’d always believed that powering up old equipment once in a while generates enough heat to dry the components out. I had one of those. Thanks for all the speedy responses.
DM74LSN (Fairchild) – 1-of-8 Line Data Selector/Multiplexer
The associate degree wasn’t even accredited the BS was though that’s why I went on for the BS at the same school after the associate degree. So now I figure I want to get some projects and practical experience under my belt before I move on for a Masters dm74lss151n yet more calculus and theory. I 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 eatasheet them before.
Cheers, Howard Winter St. I don’t know how to program PLDs but I don’t think the school even had the means to do it.
