Absolute Maximum Ratings
Absolute maximum ratings are those values beyond which damage to the device may occur. The datasheet
specifications should be met, without exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet
specifications.
