Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. Operating Range conditions indicate the conditions at which the device is functional and the device should
not be operated beyond such conditions. For guaranteed specifications and conditions, see the Electrical Characteristics table.
Note 2: Peak is the dc plus transient voltage including switching spikes.
Note 3: Human Body Model (HBM) is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. Applicable standard is JESD22-A114C. All pins
pass 2 kV HBM except VDD, VIN and VCC which are rated for 1.5 kV.
Note 4: Tested on a four layer JEDEC board. Four vias provided under the exposed pad. See JEDEC standards JESD51-5 and JESD51-7.
