Thermal Resistance
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 100 pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 3: JEDEC test board description can be found in JESD 51-5 and JESD 51-7.
Note 4: Current flow out of a pin is indicated as a negative number.
