Note 1: 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 2: For detailed information on soldering plastic MSOP and LLP packages, refer to the Packaging Data Book available from National Semiconductor
Corporation.
Note 3: All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with T
limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 4: The V
Note 5: The human body model is a 100pF capacitor discharge through a 1.5kΩ resistor into each pin. The human body ESD compliance level for Pin 7 and 8
is 1000V.
Note 6: For devices procurred in the LLP-8 package the Rds(on) limits are guaranteed by design characterization data only.
