Hi Alan > What are you talking about? > > https://www.digikey.com/product-detail/en/maxim-integrated/DS12885/DS12885-ND/1196867 Thank you for your input, however a DS12885 is not a DS1285 (and neither a DS12887/A is a DS1287/A), and I did explain why I only consider an exact replacement suitable for my use.
