I noticed the ISD4004-08MPY is listed Not for new designs". Do we know when the product will be discontinued? Is there a substitute for it?
Hello @bryan1 and welcome to the forum. I wish I had better news for you, but as of right now it doesn’t seem that we have a last time buy date or published end of life notice from the manufacturer with a date yet. I looked over our options in similar ICs but it seems that the number of active part numbers in that category overall has drastically gone down.
I’ll link the similar chips that I found below, but I wouldn’t really consider any of these a true replacement or substitute for the original.
