9DBL0841 / 9DBL0851 DATASHEET
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9DBL0841 / 9DBL0851. These ratings, which are
standard values for IDT 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.
