The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Table 4. Absolute Maximum Ratings In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND.
