Note 1:
Absolute maximum ratings are those values beyond which damage
to the device may occur. Exposure to absolute maximum rating conditions
for extended periods may affect reliability. The databook specifications
should be met, without exception, to ensure that the system design is reli-
able over its power supply, temperature, and output/input loading variables.
