Note1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. For guaranteed specifications and test conditions, see the
Electrical Characteristics
. The guaranteed specifications apply only for the test conditions listed.
Note 2: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C.
Note 3: Optimum performance is obtained at currents below 1000µA.
