These are the exact same parts (Mechanically, perhaps not performance wise), right down to the mask set which has not changed since 2001: Every layer in the set has the same revision between these two parts.
New LM4871 from Digikey: http://ppl.ug/i4CUcbOKElY/ >From the LM4871 data sheet: http://ppl.ug/j1G65GS5644/ LM4871 date code is 32AC = 2003 or 2013, weeks 12 to 17, Die run "AC" (Probably 2013 because Digikey has thousands of them. It looks like these were introduced in 1997: http://ppl.ug/n7kz2l2RUmo/) LM9022 date code is 449E = 2004, weeks 24 to 29, Die run "9E" (Not 1984 or 1994 etc as the mask set is from 2001, not 2014 as I owned these many years ago. It looks like these were released in 2001: http://ppl.ug/myU2AVIrnZc/) jt -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
