Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS9FG104E. 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.
