Note: 1. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient
temperature as possible
2. If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (<=300mA)
and high driver currents (>=30mA), it may take up to 2uS for it to come out of saturation. This condition will
shorten the off time at frequencies >= 30KHz, and is magnified at high temperature. This condition does not
occur with a Darlington configuration, since the output switch cannot saturate. If a non-Darlington configuration
is used, the following output drive condition is recommended:
Forced Bata of output switch:
Ic output / (Ic driver – 7mA*) >= 10
* The 100ohm resistor in the emitter of the driver divide requires about 7mA before the output switch conducts.
