How is the control voltage pin (pin 5) used?

What will be an ideal response?


If this pin is connected to Vcc through a variable resistor, the on time is longer, but the off time is not affected. If pin 5 is connected to ground through a variable resistor, the on time is shorter, and the off time is still not affected. If pin 5 is not to be used in the circuit, it is usually taken to ground through a small capacitor. This helps to keep circuit noise from "talking" to pin 5.
