Part III Electrical and Thermal Characteristics
This section provides the AC and DC electrical specifications and thermal characteristics for the MPC850.
Table 2 provides the maximum 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 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 MPC850 is unpowered, voltage greater than 2.5 V must not
be applied to its inputs).
The MPC850, a high-frequency device in a BGA package, does not provide a guaranteed maximum ambient
temperature. Only maximum junction temperature is guaranteed. It is the responsibility of the user to consider
power dissipation and thermal management. Junction temperature ratings are the same regardless of frequency
rating of the device.
