unknown Fairchild OpAmp

I could not find this op amp online. I think its probably a single and not a double but I cannot be sure.


I have a to-99 fairchild with a code that doesn't return anything on Google. i know it's fairchild because of the logo, but the rest of the marking is "591-101 7402"

7402 returns a 14 DIL chip, but mine is an old 8 in a round to99. Could it be fake?

found it!

catalog 1973 returns a to99 opamp with the code 101. it matches the ua741 so I think thats the ticket.

And one directory higher (https://www.rsp-italy.it/Electronics/Databooks/) lists ~100 companies, with multiple databooks under each company.
Very useful!
