Welcome to the TechForum piousjohn56! I do not see any new notices on status change for this part or the series. There is no evidence it is going obsolete any time soon. In general, DigiKey does not receive these notices well in advance. They are issued about the same time that the manufacturer updates the status.
There are a few TechForum posts that answer this generally, for reference:
- Part Status: Obsolescence Process Explained : A main explanation of the general process.
- Component reliability and longevity data for medical product - #4 by Kaleb_Kohlhase : A specific response to a customer asking a similar question.
