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, V_CC = 12VDC).
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate
power dissipation to achieve high MTTF.
3. Each of the two active output transistors can dissipate 78W.
4. Derate to 70V below T_C = +25°C.
