This circuit shows an LED flasher that uses an LM3909. Notice that the circuit is similar to that of Fig. 12-43B, except that a 1-kΩ resistor is connected between pin 4 and pin 8. This produces a little over three times the flashing rate of the Fig. 12-43B circuit. National Semiconductor Linear Applications Handbook 1991 p 395
