Electrical Characteristics
2 Electrical Characteristics
This section provides the AC and DC electrical specifications and thermal characteristics for the
MPC8306. The MPC8306 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.

Notes:
1. Functional and tested operating conditions are given in Table 2. Absolute maximum ratings are stress ratings only, and
functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause
permanent damage to the device.
2. OVDD here refers to NVDDA, NVDDB, NVDDC, NVDDF, NVDDG, and NVDDH from the ball map.
3. Caution: MV
IN
must not exceed GV
DD
by more than 0.3 V. This limit may be exceeded for a maximum of 100 ms during
power-on reset and power-down sequences.
4. Caution: OV
IN
must not exceed OV
DD
by more than 0.3 V. This limit may be exceeded for a maximum of 100 ms during
power-on reset and power-down sequences.
