2 Electrical Characteristics  
This section provides the AC and DC electrical specifications and thermal characteristics for the  
MPC8347EA. The device is currently targeted to these specifications. Some of these specifications are  
independent of the I/O cell, but are included for a more complete reference. These are not purely I/O buffer  
design specifications.  
2.1  
Overall DC Electrical Characteristics  
This section covers the ratings, conditions, and other characteristics.
