These are stress ratings 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 DS75LX is 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, the DS75LX 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 in Dallas at (972) 371-
4448.
