DM74LSN Datasheet(PDF) – Fairchild Semiconductor

I don’t know how to program PLDs but I don’t think the school even had the means to do it. Bill Original Message From: They’re supposed to be hermetically sealed but I do wonder about ingress of moisture. The dmm74ls151n output didn’t produce any output. The school had given us tons of IC chips that we never used.

Then in the bachelors degree it was all communications stuff from telcom to satellite and network protocols. Ah yes, well spotted that man. Most of witch were odd brands that are out of business now that they probably got for next to nothing. On Sep 6,at 4: The dice themselves are hermetically sealed with a thin layer of glass on the top surface except on the bonding pads. 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.

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. Send them to me I. My school didn’t give us dm47ls151n pre-stocked junkbox. Maybe it’s something else that is going on.

Other than my laser microphone I made for my capstone project I never really made anything worthwhile that wasn’t just simply following a lab manual. Anyway, I don’t think there’s any reason to expect datasheeet 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 don’t think I recognize that appearance. Thanks for all the speedy responses. OTOH, give them to students, and a lot will get thrown into the trash when then move out at the end of the year You may as well list the rest of the part numbers you have.

I had one of those. I guess it has. I am really friken tired of Laplace transforms, lol.

Pay no attention to the man behind the curtain! 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. I’d always believed that powering up old equipment once in a while generates enough heat to dry the components out. Send them to me I will recycle them in an environmentally-friendly manner! I built a PE Drum Synth in the late 70s that used, gasp, two s for storing patterns.

The pulse output was working although the voltage level kept changing witch confused me. As it stands now it could just be a mater of putting it together with more exact values and keeping the leads short ect Tuesday, September 06, 4: 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.

There only admittance test was a 12 min timed IQ test if I recall right. You or another list member just might be able to use some of them for something useful once you know what they are.

Cheers, Howard Winter St. I managed to identify about half of them and find data sheets and the other half nothing. Can definitely come up with some use for some of this stuff, expecially the drivers. OK per request here are the rest. I put together the pulse generator circuit in that datasheet. 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 used them before.


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. The core electronics in the bs consisted of all analog circuit design and analysis with mostly discrete components occasionally op amps and tons of calculus to accomplish what we previously did with simple algebra.

Hard to rm74ls151n how small memory was back then. 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. 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: Best regards, Spehro Pefhany –“it’s the network Everything else was analog or computer related in the associate degree.

I doubt anything too useful will show up in these. On 6 Sep at
