How IC 4060 is Wired as an Oscillator?
The internal oscillator of the IC 4060 can be made to oscillate just by connecting a couple of resistors to pin10 and 11 and a capacitor to pin 9. The free ends of these components are all joined together. Reset pin 12 should be grounded. Resistor at pin 11 should be roughly 10 times that of resistor at pin 10.
The resistor at pin 10 or the capacitor can be made variable, if the frequency is to be varied, otherwise fixed values may be chosen.
After completing the above configuration, connect pin 16 and pin 8 to their respective supply terminals and switch ON the supply voltage. The internal oscillator of the IC should immediately start oscillating.
The frequency of each output will be the double of the previous one and is obtained in serial order through pin 3, 2, 1, 15, 13, 14, 6, 4, 5, and 7. Thus for example if the frequency at pin 3 is 1Hz, the frequency at pin 2 will be 2Hz, at pin 1 it will be 4 Hz ,at pin 15 it will be 8Hz and so on.
The oscillator can be stopped or reset by applying a logic 1 or a positive supply to pin 12 of the IC.
The oscillator can be latched after a set period by connecting the appropriate output to pin 11 through a diode.
