ELECTRICAL CHARACTERISTICS (Continued)
Characteristics
SOFT–START SECTION
Soft–Start Current (Vshutdown = 0 V)
Soft–Start Voltage (Vshutdown = 2.0 V)
Shutdown Input Current (Vshutdown = 2.5 V)
OUTPUT DRIVERS (Each Output, VCC = +20 V)
Output Low Level
(Isink = 20 mA)
(Isink = 100 mA)
Output High Level
(Isource = 20 mA)
(Isource = 100 mA)
Under Voltage Lockout (V8 and V9 = High)
Collector Leakage, VC = +35 V (Note 7)
Rise Time (CL = 1.0 nF, TJ = 25°C)
Fall Time (CL = 1.0 nF, TJ = 25°C)
Shutdown Delay (VDS = +3.0 V, CS = 0, TJ = +25°C)
Supply Current (VCC = +35 V)
NOTE: 7. Applies to SG3525A only, due to polarity of output pulses.
