DS76KHz
∗ 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 DS76KHz 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 DS76KHz is 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 [phone].
