So you would probably need a second if you chose to go the crystal method. Dec 25, 4. Jan 6, 3, 1, How do I calculate the resistor and capacitor values I need at pins 9, 10, and 11? You are commenting using your Facebook account. Now that was interesting! It is easy therefore to forget that 74 logic is a field that dataeheet seen continuous improvement and innovation reflecting the developments elsewhere in electronics, and the most modern 74 versions hide some impressively high specifications.

Hopefully the parts are harden for metastability. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

All inputs are protected from damage due to static discharge by protection diodes to. Email required Address never made public.

One day there will be an edit button. I have looked at their products since then, still making frequency counters but now up in the GHz range. You also need to think about accuracy, you can do this with one and a RC clock setup part of the or with a crystal oscillator, your datasneet. So I can see these time domains: No doubt your HP was a better made, more professional product than the Heathkit.


CD or equivalentalthough only partially used, was selected since it contains a clock and 2. I’ve designed quite a few and circuits. Dec 26, 7. Here is the RC oscillator right off the data sheet: The alternative is to gate the incoming sign asynchronously with combinational logic and run the prescalar at the incoming signal clock domain.

The below is 1Hz crystal oscillator, it is linking from my blog. This site uses Akismet to reduce spam. CLKO goes low and resets the counter to zero all Q outputs low. If carefully layed out, Builds can operate into the GHz range.

I bought that chip from Radio Shack, long before I knew about this site or online vendors. Obviously, the part can exceed the specs, but who knows how well. For example CD or CD or anytransformation problems.

The oscillator configuration allows design of either Bc4060 or crystal-oscillator circuits.

Notify me of new comments via email. Home – IC Supply – Link. You don’t need a to turn on the LED or other device with the Timer external clock is synchronized to uC clock.

I like the idea of 74xx dual decade counters feeding 8bit latches intended for computer buses, pick right and you get tri-state output for multiplexing.

They could reach MHz without any problem. With a crystal about the lowest frequency available for a small cost is Although it does have a calibration option. A crystal can be used in a digital clock Dec 22, 5 0. Here is another that relies on the sample rate accuracy of the sound card of a pc. No need for fancy retiming etc. The magazine followed with endless frequency counters, and over the next few years the 15 or 20 MHz upper limit for the datashfet counter slowly moved up as new families of TTL came along.

The uC clock is in the order of magnitude of 10MHz and may not be accurate and you are trying to measure signal at MHz.

Argh… setup requirement, not hold requirement. Robotic Floor Cleaner Robotic floor cleaners have been available as consumer products for a number of years now but with a gradual drop in production cost and development of new technology, these cleaners are becoming cheaper.

For example CD or CD or an other similarHDSRs connected as shown in figure 11 are the solid state equivalent of an electromechanical resolver of. No heatsink was needed but they were hand-picked by individual performance testing as were the FET input transistors. Aug 23, 6, I agree that there are more complete ways to do this if you start over. T he CD or equivalentalthough only partially used, was selected since it contains a clock and 2-bit binary counter.

But if you need that frequency counter to always work, you have to be more thorough. But if you want to discuss the design he has, it has a clock crossing. By counting the pulses, you could calculate the state of the prescaler at gate shut-off and recover that lost bit of resolution.
