Electrical Characteristics
Exceeding the above specifi cations may result in permanent damage to the device or device malfunction. Operation outside of the parameters
specifi ed in the Electrical Characteristics section is not recommended.
NOTES:
(1) Tested according to JEDEC standard JESD22-A114.
(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.
