Note 7: If the output switch is driven into hard saturation (non– Darlington configuration) at low switch currents (3 300 mA) and high driver

currents (. 30 mA), it may take up to 2.0 ms to come out of saturation. This condition will shorten the off time at frequencies . 30 kHz, and is

magnified at high temperatures. 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.
