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 TSSOP package, 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: Device thermal limitations may limit usable range.
