I have a few rails of unidentified soic-8's with only "501" and on the second line "115" on them. Nothing else, no logo, no nothing.

You know what kind of product... OK...
Do you know WHERE in the product they were used? It could be an op amp, or it could be a ROM chip.
One cannot tell without at least looking at where it is on an assembly and examining some of the connected circuitry.
I know what kind of product, not a specific product, let alone that I would have schematics or an assy. The company I got the parts from (100 something) is so badly organized that they most of the time don't know their own stuff.

It's not a ROM. Could be an opamp, or line driver,...
