1) The designer must meet the case temperature specifications for individual module components.
2) Stresses greater than those listed may cause permanent damage to the device. This is a stress rating only and the device funcional
operation at or above the conditions indicated is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect reliability.
