Maximum Tolerated Ratings

This section provides the maximum tolerated voltage and temperature ranges for the MPC885/880. Table 2

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

This device contains circuitry protecting against damage due to high-static voltage or electrical fields;

however, it is advised that normal precautions be taken to avoid application of any voltages higher than

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

inputs are tied to an appropriate logic voltage level (for example, either GND or VDD).

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 MPC885/880 is unpowered, a voltage greater than 2.5 V must not be applied

to its inputs).
