TI专家好,
TI型号中E4,G4到底有什么含义?比如TL062CDE4,TL062CDG4有什么区别呢?
谢谢!

注意看这里:
:Beginning June 1, 2004, TI will change the "e" in the Pb-free finish category to a "G" when a TI device/package combination converts to a "Green" mold compound. For example, a TI device built with NiPdAu finish will have a Pb-free finish category of "e4" until a green mold compound is implemented. When implemented, the Pb-Free finish category will be changed to "G4". (Replacement of the "e" with a "G" in the Pb-Free finish category is not part of the J-STD-609 standard at this time, but will be implemented for TI products.) "G3" category is "E3" matte tin (Sn) Pb-free finish with "Green" mold compound
即2014年6月1号之后G4就是之前的E4,名字变了,芯片本身并没有什么变化
