Data Sheet Categories
In order to provide the latest information to designers, some data sheets are published before data has been fully
characterized. These data sheets are marked as “Advanced” or Preliminary” data sheets. The definition of these categories
are as follows:
Advanced
The data sheet contains initial estimated information based on simulation, other products, devices, or speed grades. This
information can be used as estimates, but not for production.
Preliminary
The data sheet contains information based on simulation and/or initial characterization. The information is believed to be
correct, but changes are possible.
Unmarked (production)
The data sheet contains information that is considered to be final.
