After dividing it by two with a flip-flop, that makes for 74s12 You can look this. A sign that you are exceeding the maximum safe clock speed is unexplained, random misbehaviour of your system.

Since it’s an iverter, and CMOS gates basically pull the output all the way to one rail or the other anyway, I figure you’re kind of giving it an extra power or ground connection through the output if you connect the input and output to oposite rails. A few other places we discussed clock oscillators: Sun May 02, 2: Page 1 of 1. Connect some adjustable voltage source to pin 2 and 3 to choose the range and frequency.

Jul 9, 2, At this speed, propagation delays and memory access times become significant and you have to spend time adding them up and ensuring you don’t exceed the CPU timings – this can get involved. You are going to encounter difficulty getting a CMOS chip to work at that frequency. If the frequency is to high, you can use 5 or 7 gates. Despite this, I have always been intrigued by digitally controlled clock generation, but PLLs were always above my understanding.


I made a jouletheif datasheey, only with 2 coils. I heard that it wasn’t too expensive to get crystals made so I thought about getting them made for the 65C02 and WDC 65CS and for other processors.

I’m just trying to make my digital pulse width analyzer more useful than just analyzing automotive injectors, typically uS to 4mS on an 8 cyl engine. Oct 12, 1. I’d say datassheet is good for 50 MHz and more, even MHz.

The frequency will be dependend on the supplied voltage. Oct 12, 3. But there no output shown in the oscilloscope.

Thu Apr 29, Nov 24, Getting Crystals Made Posted: Do you already have an account? Still need help with l ic circuit. No, create an account now. Sat May 01, If you’d tap before the transmitter coil, nothing would happen. You May Also Like: Of course, the best option would be to, where possible, use the “Picogate” devices, which would mean none were datashet wasted.

741s24 Blown charging ic, need help with replacement Posted by baronpork in forum: The reason for connecting the unused sections of the hex Schmitt inverter to the power and ground planes as shown above is to effectively reduce the power-lead inductance for better behavior at high speeds, since 74xx DIPs’ pinouts were set to be at the corners decades ago before designers could foresee rise times reaching such speeds that the lead inductance would be a problem.

Fri Apr 30, 1: No more discrete digital logic for me? Modify R1 and C1 for desired frequency. Nov 17, 6.

Posted by txfirefighter in forum: Really advanced constructors will exceed the maximum rated processor speed – but datashet you do this you datashet to be prepared for things to fail. What is the wrong with cct? I remember reading about it in these forums awhile back how someone used an AVR for an excellent programmable clock source.

Oct 2, 17, 5, A couple of the topics here where we discussed oscillators are here and here. Nov 17, 4.
