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 DS21T07 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 DS21T07 is not exposed to environmental stresses, such as burn-
in, that some industrial applications require. For specific reliability information on this product, please
