Maximum Tolerated Ratings
3 Maximum Tolerated Ratings
This section provides the maximum tolerated voltage and temperature ranges for the MPC852T. Table 1
provides the maximum ratings and operating temperatures.
Figure 2 shows the undershoot and overshoot voltages at the interface of the MPC852T.

Functional operating conditions are provided with the DC electrical specifications in Table 5. Absolute maximum ratings are
stress ratings only; functional operation at the maxima is not guaranteed. Stresses 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 V
DDH
. This restriction applies to power-up and
normal operation (that is, if the MPC852T is unpowered, a voltage greater than 2.5 V must not be applied to its inputs).
