Note 1: Absolute maximum ratings are values beyond which damage to the

device may occur. The databook specifications should be met, without excep-

tion, to ensure that the system design is reliable over its power supply, tem-

perature, and output/input loading variables. National does not recommend

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.
