I have looked for countless hours for IC's that have Motorola's stamp on them and can't find a thing about them. I scavenged these parts from a 1968 piece of technology and I am trying to study a ciruict to see how it works and I am finding no luck on these IC serial numbers. These numbers are SC2217P and SC2215P both with what I believe to be a date code of 842. Then the next one being a MC891P with a date code of 839. If anyone has any idea about these IC's that would be fantastic. I can't find these anywhere so the help would be greatly appreciated.

 

I do not understand your question. I searched on SC2217P and this was the very first hit:

Category:	FF/Latches
Description:	J-K Flip-Flop, 2-Func, Negative Edge Triggered, DTL, PDIP14

The other two parts …. I got nothing.

 

I should have specified I forgot to mention I'm looking for data sheets for these parts. I have these parts already. Like I said, I'm trying to study how a circuit works that I scavenged from an old piece of technology.
