* 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 DS12B887 built to the highest quality standards and manufactured for long term reliability.
All Dallas Semiconductor devices are made using the same quality materials and manufacturing methods. However,
standard versions of the DS12B887 are not exposed to environmental stresses, such as burn–in, that some industrial
applications require. For specific reliability information on this product, please contact the factory in Dallas at (214)
