Electrical Characteristics
Maximum Ratings
This device contains circuitry protecting against damage due to high static voltage or
electrical fields. However, normal precautions should be taken to avoid exceeding
maximum voltage ratings. Reliability of operation is enhanced if unused inputs are pulled
to an appropriate logic voltage level (for example, either GND or V
value for a pull-up or pull-down resistor is 4.7 kΩ.
In the calculation of timing requirements, adding a maximum value of one specification to
a minimum value of another specification does not yield a reasonable sum. A maximum
specification is calculated using a worst case variation of process parameter values in one
direction. The minimum specification is calculated using the worst case for the same
parameters in the opposite direction. Therefore, a “maximum” value for a specification will
never occur in the same device that has a “minimum” value for another specification;
adding a maximum to a minimum represents a condition that can never exist.
