A worse problem can occur when is decoded and a low is applied to the resets of the counters. It is also useful for designing a divide-by-n counter, for example if you want to design a digitally tuned frequency oscillator.

It may not be long enough to reset the other 2 chips reliably. What this circuit actually do?

You can also add a clocked flip-flop at the decoded output datashert give a synchronous reset for the CD I mean when counter reaches at decimal, it should stop counting and preferably reset to zero. Hi, Sorry I could not upload the datasheet of because of file size limitation so a little snippet is attached.

I have tried to search for it at google but could not get sufficient information in this regard. Yes, adding another chip cd40139 get you a max count of in binary since these are binary counters. I have to use an invertor for cascading but it is just fine.


Yes, my password is: Its a much better way to do it and personally, the only way I would do it. U won’t like what u see! Quote of the day. Posted by Ccd40193 Kohokade in forum: Preset inputs allow you to start counting from any specified value.

The counter is immediately preset to ‘7’ and counting is resumed from there. Oct 17, 68 3. Aug 8, 5. Datwsheet 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, 1. You do not have to use an inverter to cascade a or Any way thanks for such usefull replies.

Your name or email address: Aug 8, 6. I have studied data sheet and got it.

Mar 14, 20, 5, When it does, the count resumes from the preset value. Aug 8, 7. Presets are used to start counting at a particular value or to skip counts if the design requires. By counting to I assume you are counting to in binary as these are binary counters. Oct 2, 17, 5, What does this circuit actually do?


Note that since you are resetting to 0 you don’t need the preset inputs. Can I use these preset inputs for this purpose? Aug 8, 2. Help with binary counter Posted by solidrock in forum: I’ll try to workout it if is available in my local market.

Aug 8, 4. These are synchronous counters.

dtasheet How do these pins effect the counting? Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here. Jun 26, 3, 1, Can somebody simply explain me what these pins actually do? The momentary output can be a problem depending on what you hook it to. This is extremely useful if you wish to add datashee subtract a constant value. Posted by ElijahSykes in forum: Aug 8, 3. 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.

As soon as ONE of the decoded outputs changes due to reset, the reset pulse is no longer decoded, making the reset pulse datashert short. Do you already have an account?
