Unless otherwise specified, all limits guaranteed for T
(Note 8)
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 table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: For testing purposes, ESD was applied using ‘Human body model’; 1.5 kΩ in series with 100 pF
Note 3: Machine Model, 0Ω in series with 200 pF.
Note 4: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150˚C
Note 5: The maximum power dissipation is a function of T
(T
Note 6: Typical values represent the most likely parametric norm.
Note 7: All limits are guaranteed by testing or statistical analysis.
Note 8: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of
the device such that T
