Maximum Tolerated Ratings
This section provides the maximum tolerated voltage and temperature ranges for the MPC875/MPC870.
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 MPC875/MPC870.

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.
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 MPC875/MPC870 is unpowered, a voltage greater than 2.5 V must not be applied to its inputs).
