This section provides the AC and DC electrical specifications and thermal characteristics for the
MPC8349EA. The MPC8349EA 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.
