I usually use a to drive a relay for power applications, but this is not always needed. This is probably plenty good for the home workbench because a glitchy output here and there can be ignored.

You are commenting using your Facebook fatasheet. But he is running the device way, way out of spec at least per the datasheet. The high or the low is going to be 1 second each and use that to gate the counting. Previous 1 2 The only thing that is guaranteed to be running is PPS.

Q3 is on, the equivalent value of R6 and R7 in parallel becomes the constant-current programming. Manufacturer says 25 MHz is max? If carefully layed out, Builds can operate into the GHz range. The PPS is used to gate external signal. No need for fancy retiming etc. This is why there are limitations on the clock frequency for this part.

Peace and blessings, Johnny Quest and Bandit. The spec sheet says 40 MHz is the max frequency and the specified switching specs line up with that. I did this with an LS A with a watch crystal can make a very accurate 2Hz signal, which you would then drive a second circuit with.


SMD HC 4060

Though the norm at that time was a prescaler that only went up to about MHz, it was ECL and needed a heatsink. Nov 12, 3, 2, They could reach MHz without any problem.

Unless you are going to redesign the whole thing, you need to either accept that. For example CD or CD or any other similar counter may be used as dividing.

Love the dead-bug style prototyping technique. Side note, Hx4060 am assuming a Heathkit had a frequency counter out inand it was somewhere in the hundreds of dollars range. Yes, datashret password is: I agree that there are more complete ways to do this if you start over.

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

Very Simple PC Frequency Counter Works Up To 100MHz

Email required Address never made public. Although it does have a calibration option. CLKA, including well within the hold requirement. Obviously, the part can exceed the specs, but who knows hc40600 well.


This is a really cool build — especially at the price. Like I was going to impregnate her by being within 20 feet of her … weird.

Dec hd4060, 5. The oscillator configuration allows design of either RC- or crystal-oscillator circuits. I have looked at their products since then, still making frequency counters but now up in the GHz range.

Products conform to specifications per the terms of Texas Instruments standard warranty. But on the bench I use one of my old HP counters. Dec 26, 8.

Timer – Posted by Bernard in forum: If you really datsheet down this road, you are playing chase the metastability. The CD or equivalentalthough only partially used. Dec 27, No heatsink was needed but they were hand-picked by individual performance testing as were the FET input transistors. You are commenting using your Twitter account.
