Hi, Sorry I could not upload the datasheet of because of file size limitation so a little snippet is attached.

Aug 8, 8. 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.

The momentary output can be a problem depending on what vd40193 hook it to. Aug 8, 5.

CD40193 8-bit Up Down Binary Counter

Yes, my password is: I have tried to search for it at google but could not get sufficient information in this regard. Jun 26, 3, 1, The counter is immediately preset to ‘7’ and counting is resumed from there. A worse problem can occur when is decoded and a low is applied to the resets of the counters. I mean when counter reaches at decimal, it should stop counting and preferably reset to zero. I have studied ratasheet sheet and got it.


As soon as ONE of the decoded outputs changes due to reset, the reset pulse cd4193 no longer decoded, making the reset pulse very short. Oct 2, 17, 5, What does this circuit actually do? Yes, adding another chip would get you a max count of in binary since these are binary counters.

Do you already have an account? When it does, the count datqsheet from the preset value. It is also useful for designing a divide-by-n counter, for example if you want to design a digitally tuned frequency oscillator. Any way thanks for such usefull replies.

Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here. Aug 8, 2.

No, create an account now. Help with binary counter Posted by solidrock in forum: This is extremely useful if you wish to add or subtract a constant value. You May Also Like: It may not be long enough to reset the other 2 chips reliably. Aug 8, 7. Its a much better way to do it and personally, the only way I would do it.


Can somebody simply explain me what these pins actually do?

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. Your name or email address: Aug 8, 1. Quote of the day.

I have to use an invertor for cascading but it is just fine. Mar 14, 20, 5, Preset inputs allow you to start counting from daatasheet specified value.

A better solution would be to use a which has a synchronous reset.
