CD Datasheet(PDF) – Fairchild Semiconductor

This is extremely useful if you wish to add or subtract a constant value. Aug 8, 2. I have to use an invertor for cascading but it is just fine. 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. A better solution would be to use a which has a synchronous reset.

The counter is immediately preset to ‘7’ and counting is resumed from there. 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.

I’ll try to workout it if is available in my local market. Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here. You May Also Like: Pin 15, 1, 10 and 9. What does this circuit actually do?

When it does, the count resumes from the preset value. The momentary output can be a problem depending on what you hook it to. Posted by ElijahSykes in forum: Aug 8, 8.

Its a much better way to do it and personally, the only way I would do it. Hi, Sorry I could not upload the datasheet of because of dagasheet size limitation so a little snippet is attached.

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, adding another chip would get you a max count of in binary since these are binary counters. What this circuit actually do?

CD 8-bit Up Down Binary Counter

I have tried to search for it at google but could not get sufficient information in this regard. Aug 8, 6. Posted by Ajinkya Kohokade in forum: Aug 8, 7. Yes, my password is: Can somebody simply explain me what these pins actually do?

Any way thanks for such usefull replies. What Preset inputs actually do? Aug 8, 5. Jun 26, 3, 1, Aug 8, 4. Do you already have an account?

No, create an account now. Help with binary counter Posted by solidrock in forum: By counting to I assume you are counting to in binary as these are binary counters.

Oct 2, 17, 5, These are synchronous counters.

U won’t like what u see! Is there any way to do this?

CD40193 8-bit Up Down Binary Counter

Mar 14, 20, 5, 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. You can also add a clocked flip-flop at the decoded output to give a synchronous reset for the CD Quote of the day.

Preset inputs allow you to start counting from any specified value. Note that since you are resetting to 0 you don’t need the preset inputs.
