Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters

specified in the Electrical Characteristics section is not recommended.

Notes:

(1)

Tested according to JEDEC standard JESD22-A114-B.

(2)

Calculated from package in still air, mounted to 3 x 4.5 (in), 4 layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.

(3)

Based upon lab measurement on EVB board: 3 x 2 (in), 4 layer FR4 PCB with thermal vias under the exposed pad.
