This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the
operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of
time may affect device reliability.
Note: The DS1855 is built to the highest quality standards and manufactured for long-term reliability. All DS1855s
are made using the same quality materials and manufacturing methods. However, the DS1855 in the flip-chip
package is not exposed to environmental stresses, such as burn-in, that some industrial applications require. For
specific reliability information on this product, contact the factory.
