2.2.1. Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the STAC9271/9272/9273/9274. 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.
