Note 5:
Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply
temperature, and output/input loading variables. National does not recom-
mended operation of SCAN outside of recommended operation conditions.
