Note 1: DC Electrical Test.
Note 2: AC Electrical Test.
Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions
which guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where
no limit is given, however, the typical value is a good indication of device performance.
Note 4: All voltages are measured with respect to the ground (pin 8), unless otherwise specified.
Note 5: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum
allowable power dissipation is PDMAX = (TJMAX -TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For operating at case tempera-
tures above 25C, the device must be derated based on a 150C maximum junction temperature and a thermal resistance of
θJC = 5C/W (junction to case).
Note 6: Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 7: Machine model, 200 pF–240 pF discharge through all pins.
Note 8: Typicals are measured at 25C and represent the parametric norm.
Note 9: Limits are guarantees that all parts are tested in production to meet the stated values.
