Electrical Specifications
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 each device's data sheet is not implied. Exposure to ab-
solute maximum rating conditions for extended periods may adversely affect reliability.
