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 1.5 k

Ω resistor into each pin.

Note 3: Measurements are performed on a 4 layer JEDEC board with 10 vias provided under the exposed pad. See JESD51–1 to JESD51–11. The value of
