Obsolescence management is as much art as science (sometimes I wish there really was a crystal ball available). Is it true that DIP chips and ICs are going to be obsolete in the near future? At the risk of trying to see into the future by looking at past and current trends, I really don't think so; existing parts may slowly drop DIP packaging but it ...
