Electrical Characteristics All voltages are referenced to ground (GND). Positive currents flow into the IC. 2.1 Absolute Maximum Ratings In accordance with the Absolute Maximum Rating System (IEC60134). The absolute maximum ratings given in the table below are limiting values that do not lead to a permanent damage of the device but exceeding any of these limits may do so. Long term exposure to limiting values may affect the reliability of the device. Reliable operation is only specified within the limits shown in „Operating conditions”.
