Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS548-05. 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.
