If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents ( 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 occure with a Darlington configuration, since the output
switch cannot saturate. If a non-Darlington configuration is used, the following output drive condition is recommended.
