The counter is immediately preset to ‘7’ and counting datasheeg resumed from there. Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here.

How do these pins effect the counting?

You can also add a clocked flip-flop at the decoded output to give a synchronous reset for the CD You do not have to use an inverter to cascade a or Posted by Ajinkya Kohokade in forum: When it does, the count resumes from the preset value. I have studied data sheet and got it. These are synchronous counters. Oct 17, 68 3. As soon as ONE of the decoded outputs changes due to reset, the reset pulse is no longer decoded, making the reset pulse very short. To shorten the count, you would need to decode the bit pattern corresponding to one past and apply the decoded output to the reset input to clear the counter.


This is extremely useful if you wish to add or subtract a constant value. U won’t like what u see!

Oct 2, 17, 5, Aug 8, 1. This is used, for example, when designing a frequency counter for a radio receiver where you need to add or subtract the intermediate frequency IF from the local oscillator frequency. Aug 8, 4. Its a much better way to do it and personally, the only way I would do it. Aug 8, 7. Yes, adding another chip would get you a max count of in binary since these are binary counters.

Quote of the day.

Your name or email address: Help with binary counter Posted by solidrock in forum: A better solution would be to use a which has a synchronous reset. A worse problem can occur when is decoded and a low is applied to the resets of the counters.

Aug 8, 5. Pin 15, 1, 10 and 9. Is there any way to do this? You May Also Like: Can somebody simply explain me what these pins actually do?


It may not be long enough to reset the other 2 chips reliably. Any way thanks for such usefull replies.

I’ll try to workout it if is available in my local market. Do you already have an account?

What this circuit actually do? Note that since you are resetting to 0 you don’t need the preset inputs. Mar 14, 20, 5, Preset inputs allow you to start counting from any specified value. By counting to I assume you are counting to in binary as these are binary counters. I mean when counter reaches at decimal, it should stop counting and preferably reset to datashet. Domino’s is beginning trials for “Domino’s Robotic Unit” or DRU, so we thought we’d take a look at some more delivery robots.

It is also useful for designing a divide-by-n counter, for example if you want to design a digitally tuned frequency datashheet. The momentary output can be a problem depending on what you hook it to.
