Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 92HD81. These rat-
ings, 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 sec-
tions 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.
