Note 1. I6, I7, and I8 are limited by SOAR protection circuit that ensures that a short–circuit between

the output Pin7 and supply voltage or GND does not destroy the output stage. A short circuit
may be soldered into the printed circuit board or may sometimes (non–periodically) occur
in the applied circuit.

Note 2. The maximum value to the operating ambient temperature range and the power dissipation

depends on the heatsink.
Note 3. Internally liminted by thermal protection: switching temperature point at TJ = +150°C ±8°C.
Note 4. Human body model: 1.5kΩ, 100pF, 5 pulses.
