We currently use part DS8923AM/NOBP in our production and are aware it is currently obsolete. We came across part DS8923M in our inventory which is a model released prior to the part we currently use. I am aware that DS8923M was an National Semi product before TI acquired them and changed the orderable part numbers. We also know that the data rate for the DS8923AM/NOPB is 10Mb/s but are unable to locate the data rate of the DS8923M. Is this information you might be able to provide?
