      I'm sure it's come up in the past, but that's ok, after all, that's what this message board is all about.

      How to tell when a 3 digit date code is talking about 1970's or 1980's?
      I'm going to hope by 1990 they were seeing value in writing 2 digit year codes.

      I have here a CD74HC373E from RCA, date code is 441.  Is this 1974? or 1984?
      If it was an LS device, I would safely guess 1974, but when did the HC family come out?
