This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Maximum ambient temperature is a function of device junction temperature and system level considerations, such as power dissipation
and board layout. See dissipation rating table and recommended operating conditions for specific information related to these devices.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Surges per EN61000-4-2, 1999 applied between USB and output ground of the TPS2560EVM (HPA424) evaluation module
(documentation available on the Web.) These were the test level, no the failure threshold.
