Electrical and Thermal Characteristics

maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused

inputs are tied to an appropriate logic voltage level (either GND or VCC).

Figure 2 shows the undershoot and overshoot voltage of the 60x and local bus memory interface of the

MPC8280. Note that in PCI mode the I/O interface is different.
