What Preset inputs actually do? Aug 8, 1.

Oct 17, 68 3. Hi, Sorry I could not upload the datasheet of because of file size limitation so a little snippet is attached. Can somebody simply explain me what these pins actually do?

Pin 15, 1, 10 and 9. How do these pins effect the counting?

I have tried to search for it at google but could not get sufficient information in this regard. Aug 8, 2. Oct 2, 17, 5, Preset inputs allow you to start counting from any specified value.

This is extremely useful if you wish to add or subtract a constant value. 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.

It is also useful for designing a divide-by-n counter, for cd0193 if you want to design a digitally tuned frequency oscillator. Aug 8, 3.

Jun 26, 3, 1, When it does, the count resumes from the preset value. The counter is immediately preset to ‘7’ and counting is resumed from there. Presets are used to start counting at a particular value or to skip counts if the design requires. Aug 8, 4. I mean when counter reaches at decimal, it should stop counting and preferably reset datsheet zero.

Is there any way to do this? Can I use these cx40193 inputs for this purpose?

National Semiconductor

Aug 8, 5. Yes, adding another chip would get you a max count of in binary since these are binary counters. 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. A worse problem can occur when is decoded and a low is applied to the resets of the counters.

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. It may not be long enough to datasheey the other 2 chips reliably. Some additional circuitry to ensure that the reset pulse is stretched would be appropriate here.

A better solution would be to use a which has a synchronous reset. Its a much better way to do it and personally, the only way Ratasheet would do it. Note that since you are resetting to 0 you don’t need the preset inputs.

By counting to I assume you are counting to in binary as these are binary counters. Aug 8, 6.

Mar 14, 20, 5, You can also add a clocked flip-flop at the decoded output to give a synchronous reset for the CD Aug 8, 7. I have studied data sheet and got it. I have to use an invertor for cascading but it is just fine. I’ll try to workout it if is available in my local market.

Any way thanks for such usefull replies. Aug 8, 8. You do not have to use an inverter to cascade a or These are synchronous counters. What this circuit actually do?
