Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the 9SQL4958. 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.
