... Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz the PA81J and PA82J, signal slew rates at pins 5 and 6 must be limited to less than 1V/ns to avoid damage. When faster waveforms are unavoidable, resistors in series with those pins, limiting current to 150mA will protect the amplifier from damage. ...

... The 12 volt supply in this case must supply only the quiescent current of the PA81J, which is 8.5mA maximum. If the load is reactive or EMF producing, the low voltage supply must also be able to absorb the reverse currents generated by the load. ...
