Note 1: Absolute Maximum Ratings are values beyond which the device may be

damaged or have its useful life impaired. 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. Fairchild does not recommend

operation outside databook sepcifications.
