Not Recommended for New Designs
The MAX495 was manufactured for Maxim by an outside wafer
foundry using a process that is no longer available. It is not
recommended for new designs. A Maxim replacement or an industry
second-source may be available. The data sheet remains available for
existing users.
The other parts on the following data sheet are not
affected.
For further information, please see the QuickView data sheet for this
part or contact
