MK1725
Quad Output Spread Spectrum Clock Generator
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK1725. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
