Thermocouple effects may cause permanent damage to the device. Exposure to any Absolute preclude measurements of these voltage levels during automated testing. Maximum Rating condition for extended periods may affect device Note 4: Limit is determined by high speed automated test capability. See reliability and lifetime.
