Electrical Characteristics
The following specifications apply for V
Limits apply for T
Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2: “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 3: For operating at case temperatures above 25˚C, the device must be derated based on a 150˚C maximum junction temperature and a thermal resistance of
Note 4: Human body model, 100 pF discharged through a 1.5 k
Note 5: Machine Model 220pF−240pF discharged through all pins.
Note 6: The operating junction temperature maximum is 150˚C.
Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
