Note 4: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 5: For detailed information on soldering plastic MSOP and LLP packages, refer to the Packaging Data Book available from National Semiconductor
Corporation.
Note 6: All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with TA =TJ = 25C. All hot and cold limits
are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 7: The VCC output is intended as a self bias for the internal gate drive power and control circuits. Device thermal limitations limit external loading.
Note 8: The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 9: For devices procured in the LLP-8 package the Rds(on) limits are guaranteed by design characterization data only.
Note 10: "Testing and other quality control techniques are used to the extent deemed necessary to ensure product performance over the specified temperature
range. Product may not necessarily be tested across the full temperature range and all parameters may not necessarily be tested. In the absence of specific
PARAMETRIC testing, product performance is assured by characterization and/or design."
