Functional Description
The IC 4024 is a 14-stage binary ripple counter. The counter increments on the rising edge of the clock input (CP). The divide-by-two section produces a half-frequency output on output 6 (Q6). The reset input (MR) resets the counter to zero when it is pulled low.
There are 7 outputs for the IC 4024. The outputs are Q1, Q2, Q3, Q4, Q5, Q6, Q7.
The number beside the Q indicates by what figure it divides the input pulses to produce a divided output.
Let's take the example of pin#3 which is a Q7 output.
Q7 means, it divides the input pulses at pin#1 by 27 = 128.
If, let's assume that the clock frequency at pin#1 is 512 Hz, then this 512 will be divided at the output pin#7 by 128. The result will be 512 / 128 = 4 Hz.
Therefore, if there's a 512 Hz frequency at pin#1 then pin#7 will divided it by 2 to generate a 4 Hz frequency.
The same applies for the other outputs. For example pin#4 which is Q6 will divide by 26 , pin#5 which is Q5 will divide by 25 ans so on.
