NOTES:
1. All Min/Max characteristics and specifications are guaranteed over the Specified Operating Condi-
tions. Typical performance characteristics and specifications are derived from measurements taken
at typical supply voltages and T_C = 25°C.
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate
internal power dissipation to achieve high MTTF. For guidance, refer to the heatsink datasheet.
3. 40W in each of the two active output transistors on at any one time.
4. Min max values guaranteed but not tested.
