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 devices
should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
Note 2: Derate CDip = 11.5 mW/˚C, CLCC = 13mW/˚C, Cerpack = 7.4mW/˚C above 25˚C.
Note 3: Parameter tested go-no-go only.
Note 4: Subgroups 1, 2 and 9, 10: Power dissipation must be externally controlled at elevated temperatures.
Note 5: Pre and post irradiation limits are identical to those listed under AC and DC electrical characteristics. These parts may be dose rate sensitive in a space
environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters are guaranteed only for the conditions as specified
in MIL-STD 883, Method 1019, Condition A.
Note 6: Subgroup 10 and 11 guaranteed but not tested.
