These are synchronous counters. What does this circuit actually do? You May Also Like: I have studied data sheet and got it. Hi, Sorry I could not upload the datasheet of because of file size limitation so a little snippet is attached.

Your name or email address: This is extremely useful if you wish to add or subtract a constant value. Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here.

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.

Preset inputs allow you to start counting from any specified datasheey. By counting to I assume you are counting to in binary as these are binary counters.

I have tried to search for it at google but could not get sufficient information in this regard. Can I use these preset inputs for this purpose? Aug 8, 8. Aug 8, 1. I’ll try to workout it if is available in my local market. Oct 2, 17, 5, 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.

The momentary output can be a problem depending on what you hook it to. You do not have to use an inverter to cascade a or Pin 15, dataaheet, 10 and 9. Aug 8, 7.

Aug 8, 4. What this circuit actually do? A better solution would be to use a which has a synchronous reset. Oct 17, 68 3. I mean when counter reaches at decimal, it should stop counting and preferably datashwet to zero.

Aug 8, 2. U won’t like what u see!

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. A worse problem can occur when is decoded and a low is applied to the resets of the datashfet.


It may not be long enough to reset the other 2 chips reliably. How do these pins effect the counting? 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.

Note that since you are resetting to 0 you don’t need the preset inputs. What Preset inputs actually do? I have to use an invertor for cascading but it is just fine.

Its a much better way to do it and personally, the only way I would do it. Yes, adding another chip would get you a max count of in binary since these are binary counters. It is also useful for designing a divide-by-n counter, for example if you want to design a digitally tuned frequency oscillator.

The counter is immediately preset to ‘7’ and counting is resumed from there. Can somebody simply explain me what these pins actually do?
