7)

Added note clarifying DC electrical test conditions.

 

 

 

8)

Added note clarifying VOH3 specification applies to first clock cycle following the transition.

 

 

 

9)

Updated AC and MOVX electrical characteristics with final characterization values.

 

 

 

10) Added tAVLL2 specification and corrected MOVX timing diagrams to show tAVLL2 instead of tAVLL.

 

 

 

11) Updated IBAT to incorporate errata conditions.

 

 

112299

Contact factory for details.
