Note 1: 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-

mend operation outside of databook specifications.

Note 2: All commercial packaging is not recommended for applications re-

quiring greater than 2000 temperature cycles from −40˚C to +125˚C.
