Do you have more info on where you heard about "7300 series"?
My usual sources of information on old logic IC families yields no results.

Acording to 70s databook 5300s and 7300s are "Modified DTL" (in lieu of 5400 and 7400 being TTL?)
The sequence aren't interchangeable. 7300 for example is a JKFF
