3 / 18 page ![]() 3/18 L9848 ABSOLUTE MAXIMUM RATINGS For voltages and currents applied externally to the device. This part may be irreparably damaged if taken out- side the specified absolute maximum rating range (*) Internally limited OPERATION CONDITIONS This part may not operate if taken outside the maximum ratings. Once the condition is returned to within the specified maximum rating or the power is re-cycled, the part will recover with no damage or degradation.
