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:
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 3:
V
CC
provides bias for the internal gate drive and control circuits. Device thermal limitations limit external loading.
Note 4:
For detailed information on soldering plastic TSSOP and LLP packages refer to the Packaging Data Book available from National Semiconductor
Corporation.
Note 5:
Typical specifications represent the most likely parametric norm at 25C operation.
Note 6:
All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with T
A
= 25C. All hot and cold limits are
guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
