Electrical Characteristics
This section provides the AC and DC electrical specifications and thermal characteristics for the
MPC8378E. 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.
