Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.

Note 2: The FSP4054 is guaranteed to meet performance specifications from 0°C ~ 70°C. Specifications over the

-40°C ~85°C operating temperature range are assured by design, characterization and correlation with

statistical process controls.
