* 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 DS1307/DS1308 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 DS1307/DS1308 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 information on this product,
please contact the factory at (972) 371-4448.
