Stresses greater than those listed may cause permanent damage to the module. This is a
stress rating only, and functional operation of the module at these or any other condi-
tions outside those indicated in the device data sheet are not implied. Exposure to
absolute maximum rating conditions for extended periods may adversely affect reliability.
