Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Tests are performed as shown in the configuration of Figure 2.
Note 3: Specifications over the – 40 C to 85 C temperature range are
assured by design, characterization and correlation with statistical process
control.
