Thermal Resistance (Note 6)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and conditions see the Electrical Characteristics.
Note 2: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 3: Current out of a pin is indicated as a negative value.
Note 4: For detailed information on soldering plastic MSOP and LLP packages refer to the Packaging Databook available from National Semiconductor
Corporation.
Note 5: Maximum continuous current into VCC is limited by power dissipation and die temperature. See the Thermal Considerations section.
Note 6: Tested on a 4 layer JEDEC board with 2 vias under the package. See JEDEC standards JESD51-7 and JESD51-3. See the Thermal Considerations
section.
