* 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 reliability.
The Dallas Semiconductor 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, please
