Electrical Characteristics

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

MPC8323E. The MPC8323E 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.

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. Caution: MVIN must not exceed GVDD 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.

3. Caution: OVIN must not exceed OVDD 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. (M,O)VIN and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.

5. OVIN on the PCI interface may overshoot/undershoot according to the PCI Electrical Specification for 3.3-V operation, as

shown in Figure 3.
