* 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 DS1302 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,
standard versions of the DS1302 are not exposed to environmental stresses, such as burn–in, that some industrial
applications require. Products which have successfully passed through this series of environmental stresses are
marked IND or N, denoting their extended operating temperature and reliability rating. For specific reliability informa-
tion on this product, please contact the factory in Dallas at (972) 371–4448.
