Note 1: Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device

should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.

Note 2: Derate J package 11.11 mW/˚C above 25˚C; derate E package 12.5 mW/˚C above 25˚C; derate W Package 6.4516 mW/˚C for above 25˚C.

Note 3: Human body model, 1.5k

Ω in series with 100pF.

Note 4: Parameter tested go-no-go only.

Note 5: For Subgroups 1 and 2, power dissipation must be externally controlled at elevated temperatures.

Note 6: Tested at 25˚C, guaranteed but not tested at +125˚C & −55˚C
