Maximum Tolerated Ratings

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 VCC).

The power supply of the device must start its ramp from 0.0 V.

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 the supply voltage. This restriction

applies to power-up and normal operation (that is, if the MPC862/857T/857DSL is unpowered, voltage greater

than 2.5 V must not be applied to its inputs).

Minimum temperatures are guaranteed as ambient temperature, TA. Maximum temperatures are guaranteed as

junction temperature, Tj.

JTAG is tested only at ambient, not at standard maximum or extended maximum.
