∗ 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
