Maximum Tolerated Ratings
This section provides the maximum tolerated voltage and temperature ranges for the MPC853T. Table 1 provides
the maximum ratings and the operating temperatures.
This device contains circuitry protecting against damage caused by 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, VDDL, or VDDH).

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. 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 MPC853T is unpowered, a voltage greater than 2.5 V must not be applied to
its inputs).
