Having the higher order bits is in many applications more useful than the low order bits, so the designer chose to break them out. So everything is working correctly.

It has 12 output pins ranging from Q1 to Q14 excluding Q2 and Q3. Both devices are incremented on the falling edge negative transition of the input clock, and all their outputs are reset to a low level by applying a logical high on their reset input.

No, create an account now. Negative current come from the convention that ALL current flows into the device, so any current flowing ou of the device is negative. Note also that it is a stage counter, which means the counter internally has 14 outputs. Yes, my dqtasheet is: From Q1 you will get a nice digital clock signal out, albeit at half the frequency of the oscillator.

Do you already have an account? Home Questions Tags Users Unanswered. However the next available output is Q4 – this will be the fourth bit in the counter.

CD4020 – 14-Bit Binary Counter

Alexander in fact that is then one possible use for the Q1 – it will give you a nice clock signal from a narrow pulsed input. You May Also Like: I have connected the ripple counter CD to an Atmega, which sends datasehet 50ms low logic level pulse to the CD’s input each second and monitors all of its 12 outputs.

Do you see that there is no Q2 or Q3 output? Sign up or log in Sign up using Google. The datasheet also states, that the CD is a stage counter, but it only has 12 outputs. Then the output datahseet will go high at the following time intervals shown in table below.

But, Alexander, the information is otherwise completely correct: For each clock signal the binary value gets incremented by one. A clear input is used. Your name or cd datasheet address: Why ripple counter increments on each 8th pulse Ask Question. Q1 is the first datasheef in the counter. To be a little nit-picky, it’s not clocked and it’s negative edge sensitive.
