(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and 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. The Recommended Operating Conditions
indicate conditions at which the device is functional and the device should not be operated beyond such conditions. Absolute Maximum
Numbers are ensured for a junction temperature range of -40°C to +125°C. Models are validated to Maximum Operating Voltages only.
7.2 ESD Ratings
V_(ESD) Electrostatic discharge

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Pins listed as ±4500
V may actually have higher performance.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Pins listed as ±1500
V may actually have higher performance.
7.3 Recommended Operating Conditions

(1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
(2) No heat sink is assumed for these estimations. Depending on the application, a heat sink, faster air flow, and/or reduced ambient
temperature ( < 85ºC) may be required in order to maintain the maximum junction temperature specified in Electrical Characteristics.
