Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
These parameters are guaranteed by design. Thermocouple effects may cause permanent damage to the device. Exposure to any Absolute preclude measurement of these voltage levels in high speed automatic Maximum Rating condition for extended periods may affect device test systems. VOS is measured to a limit determined by test equipment reliability and lifetime. capability. 6800fb Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Applications Information Typical Applications Package Description Revision History Related Parts Typical Application
