Clamp current 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.
