Exceeding the Absolute Maximum Ratings may result in permanent damage to the device or device malfunction. Operation outside of the Rec-

ommended Operating Conditions is not recommended.

NOTES:

() Tested according to JEDEC standard JESD22-A4-B.

(2) Calculated from package in still air, mounted to 3” x 4.5”, 4 layer FR4 PCB with thermal vias under the exposed pad per JESD5 standards.
