Maximum Tolerated Ratings

This section provides the maximum tolerated voltage and temperature ranges for the MPC852T. Table1 provides

the maximum ratings and operating temperatures.

This device contains circuitry protecting against damage that high-static voltage or electrical fields cause; however,

Motorola recommends taking normal precautions 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). -- VDDH.

Thermal Characteristics

Input voltage 2

Functional operating conditions are provided with the DC electrical specifications in Table5.

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 VDDH. 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).
