7.1 DC Characteristics
7.1.1 Maximum Guaranteed Ratings
Stresses beyond those listed in may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
7.1.1.1 Human Body Model (HBM) Performance
HBM testing verifies the ability to withstand the ESD strikes like those that occur during handling and
manufacturing, and is done without power applied to the IC. To pass the test, the device must have
