Electrical Characteristics

This section provides the AC and DC electrical specifications and thermal characteristics for the

MPC8377E. 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.
