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

specified in the Electrical Characteristics section is not implied. Exposure to Absolute Maximum rated conditions for extended periods of time

may affect device reliability.

Note:

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