Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of the device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T_J(MAX), θ_JA , and the ambient temperature T_A. The maximum
allowable power dissipation is P_DMAX = (T_JMAX − T_A) / θ_JA or the number given in the Absolute Maximum Ratings, whichever is lower.
Note 4: Human body model, applicable std. JESD22–A114C.
Note 5: Machine model, applicable std. JESD22–A115–A.
Note 6: Typical values represent the most likely parametric norms at T_A = +25°C, and at the Recommended Operation Conditions at the time of product
characterization and are not guaranteed.
Note 7: Datasheet min/max specification limits are guaranteed by test or statistical analysis.
Note 8: Slew rate is the average of the rising and falling slew rates.
Note 9: Average Temperature Coefficient is determined by dividing the changing in a parameter at temperature extremes by the total temperature change.
Note 10: Short−Circuit test is a momentary test. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed
junction temperature of 150°C.
Note 11: Positive current corresponds to current flowing into the device.
