I have tried to search for it at google but could not get sufficient information in this regard. 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. Yes, my password is: This is extremely useful if you wish to add or subtract a constant value.

These are synchronous counters. A worse cd40139 can occur when is decoded and a low is applied to the resets of the counters. I have to use an invertor for cascading but it is just fine.

You do not have to use an inverter to cascade a or By counting to I assume you are counting to in binary as these are binary counters. What does this circuit actually do?

I mean when counter reaches at decimal, it should stop counting and preferably reset to zero. Quote of the day. Mar 14, 20, 5, Do you already have an account? Pin 15, 1, 10 and 9. I’ll try to datashwet it if datadheet available in my local market. U won’t like what u see!


It is also useful for designing a divide-by-n counter, for example if you want to design a digitally tuned frequency oscillator.

CD40193 Binary U/D Counter help. What Preset inputs actually do?

Aug 8, 8. Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here. Your name or email address: Can somebody simply explain me what these pins actually do? When it does, the count resumes from the preset value.

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. Jun 26, 3, 1, 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.

What this circuit actually do? Any way thanks for such usefull replies. Oct 2, 17, 5, What Preset inputs actually do?

How do these pins effect the counting? Aug 8, 1. Aug 8, 2. 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. Aug 8, 3. Can I use these preset inputs for this purpose? A better solution would be to use a which has a synchronous reset. Presets are used to start counting at a particular value or to skip counts if the design requires.


Note that since you are resetting to 0 you don’t need the preset inputs. It may not be long enough to reset the other 2 chips reliably.

Help with binary counter Posted by solidrock in forum: Aug 8, 5. I have studied data sheet and got it.

CD 8-bit Up Down Binary Counter

Aug 8, 6. This is used, for example, when designing a frequency counter for a radio receiver where you need to add or subtract the intermediate cc40193 IF from the local oscillator frequency.
