So I have a socketed chip that I noticed has a leg broken off of it. It's a SN747LS626N. Of course I can't find one of these, but it looks like arcadepartsandrepair has a SN74LS629N. The specs look the same so I am assuming I can just get one of these and be fine. I don't know enough about electronics to know for sure though so I thought I would ask. Why do these old chips obsolescence and why do they replace them with newer chips that seem to be the same speck wise? What's the deal with that.... curious minds want to know....
