3) If Darlington configuration is not used, care must be taken to avoid deep saturation of output switch.
The resulting switch-off time may be adversely affected.
In a Darlington configuration the following output driver condition is suggested:
Forced β of output current switch= I

Current less due to a built in 1K antileakage resistor.
4) Start-up Voltage is the minimum Power Supply Voltage at which the internal oscillator begains to work.
