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.

The maximum power dissipation is PD(MAX) = (T ) - T ) / JA where T is 125C. Exceeding the maximum allowable power dissipation will result in excessive die temperature, J(MAX A J(MAX) and the device will enter thermal shutdown. 2. This thermal rating was calculated on JEDEC 51 standard 4-layer board with dimensions 3 x 4.5 in still air conditions. 3. Actual thermal resistance is affected by PCB size, solder joint quality, layer count, copper thickness, air flow, altitude, and other unlisted variables.
