8. 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 m s 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.
