16. Definitions
Short-form specification — The data in a short-form specification is 
extracted from a full data sheet with the same type number and title. For 
detailed information see the relevant data sheet or data handbook. 

Limiting values definition — Limiting values given are in accordance with 
the Absolute Maximum Rating System (IEC 60134). Stress above one or 
more of the limiting values may cause permanent damage to the device. 
These are stress ratings only and operation of the device at these or at any 
other conditions above those given in the Characteristics sections of the 
specification is not implied. Exposure to limiting values for extended periods 
may affect device reliability.
