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 VDDH).

2 Functional operating conditions are provided with the DC electrical specifications in Table 6. 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 MPC875/870 is unpowered, a voltage greater than 2.5 V must not be applied
to its inputs).
