IC 4060 Pinouts Explained


Another versatile device, the IC 4060 has numerous
applications and can be used for implementing various useful functions in an
electronic circuit.


Basically the IC 4060 is a oscillator/Timer IC and can be
used for producing discretely variable accurate time intervals or delays or
alternatively it may  also be used as an
oscillator for acquiring high grade, accurate time period oscillations of
frequencies.

The best thing about this chip is that it has an in-built oscillator
module which requires just a few external components for initiating the
oscillations.

Thus the IC is not dependant on any external clock input.
Let’s try to understand the pin outs of the IC 4066 through
simple words:
Referring to the figure we see that the only input pins
which require to be configured are pin # 9, 10, 11, and 12, the all the
remaining pin outs are the outputs of the IC.
The outputs are assigned for producing the time delays or
the clock signals or the oscillations or the frequency at different levels. Pin
#7 generates the highest number of frequencies for a set level, while pin #3
produces the least.
Therefore, suppose if pin # 7 generates a frequency
of 1MHz, pin #5 will generate a frequency of 500 Khz, pin # 4 generates 250 Khz,
pin #6 generates 125KHz, pin #14 generates 62.5 KHz and so on, the frequency
becomes half, in the order of the pin outs 7,5,4,6,14,13,15,1,2,3
The above frequency or oscillations can be initiated by
connecting a few passive components at pin #9, 10 and 11 of the IC as shown in
the figure, it’s that simple.
The variable resistor is used to vary the frequency to any
desired level, the capacitor value may also be altered for changing the
frequency of the IC.
Pin #12 is the reset input and should always be grounded or
connected to the negative supply. A positive supply pulse to this input will
reset the oscillations or revert the IC so that it begins counting or
oscillating from the beginning.
Pin #16 is the positive of the IC and pin #8 is the negative
supply input of the IC.
