Maximum Tolerated Ratings

This section provides the maximum tolerated voltage and temperature ranges for the MPC885/MPC880.

Table 2 displays the maximum tolerated ratings, and Table 3 displays the operating temperatures.

Figure 3 shows the undershoot and overshoot voltages at the interfaces of the MPC885/MPC880.

Input voltage2

2 Functional operating conditions are provided with the DC electrical specifications in Table 6. Absolute maximum ratings are

stress ratings only; functional operation at the maxima is not guaranteed. Stress beyond those listed may affect device

reliability or cause permanent damage to the device. See Section 8, “Power Supply and Power Sequencing.”

Caution: All inputs that tolerate 5 V cannot be more than 2.5 V greater than VDDH. This restriction applies to power up and

normal operation (that is, if the MPC885/MPC880 is unpowered, a voltage greater than 2.5 V must not be applied to its inputs).
