Yes, the either side of that gating can violate timings, so worse case you have 2 glitches hat might violate timing datashewt the prescaler.

We all use 74 logic in our projects as general purpose logic interfacing glue. Leave a Reply Cancel reply Enter your comment here Well I was thinking of the HP we had where I first worked, that cost, as I recall being told, over two grand in Unless you are going to redesign the whole thing, you need to either accept that.

Dec 25, 3.

Dec 26, 7. No need for fancy retiming etc. After the clock is deasserted, count the number of pulses that cause the prescaler output to advance i. The point is, it was convenient to get this chip at that time.

Previous 1 2 I usually use a to drive a relay for power applications, but this is not always needed. On all other products, production processing does not necessarily include testing of all parameters.


Jan 29, 6, 1, On all other products, production. I bought that chip from Radio Shack, long before I knew about this site or online vendors.

All inputs are protected from damage due to static discharge by protection diodes.

SMD HC 4060

A RC can use just one chip plus the timer. Though those prescale by some binary number, not a neat ten that makes it easy to use with an existing frequency counter.

Somewhere in the ‘s IIRC. You are commenting using your Facebook account. The only thing that is guaranteed to be running is PPS.

For example CD or CD or any other similar counter may be used as dividing. Hopefully the parts are harden for metastability. 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 choice. This is probably plenty good for the home workbench because a glitchy output here and there ch4060 be ignored.

Obviously, the part can exceed the specs, but who knows how well. It is easy therefore to forget that 74 logic is a field that has seen continuous improvement and innovation reflecting the developments elsewhere in dxtasheet, and the most modern 74 versions hide some impressively high specifications. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of. Argh… setup requirement, not hold requirement.


Very Simple PC Frequency Counter Works Up To 100MHz

Oct 2, 5, 1, So I can see these time domains: How do I calculate the resistor and capacitor values I need at pins datashedt, 10, and 11? Love the dead-bug style prototyping technique.

A with a watch crystal can make a very accurate 2Hz signal, which you would then drive a second circuit with. In the datasheet, they have a diagram which shows all of this.

Nov 4, I think that for anyone wanting to build a frequency counter at home, that living with 1 is fine. 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. Ic cd pin diagram Abstract: I agree that there are more complete ways to do this if you hc400 over.
