Once a final customer configuration has been defined, a configuration specific -xx ID will be assigned and used for order and marking. ABSOLUTE MAXIMUM RATINGS Stresses above the ratings listed below can cause permanent damage to the IDTP9122. These ratings 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.
