Quote of the day. And reduced down to 2. Of course, the best option would be to, where possible, use the “Picogate” devices, which would mean none were left wasted.

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.

Despite this, I have always been intrigued by digitally controlled clock generation, but PLLs were always above my understanding.

Nov 17, Hello, Did you see my last remark in my previous post? It does get hot though, which means it is using quite abit of current I think about mA. I’d say this is good for 50 MHz and more, even MHz.

Embedded Systems and Microcontrollers. Hello, I need a After dividing it by two with a flip-flop, that makes for Since there is no typical cct mentioned in the 74S datasheet, I datasheft the following circuit diagram and observed the output.

I tried using a inverter see attachment for configurationand after removing the capacitor and lowering the value of R to the point just before oscillation stopped, I measured a frequency of 5 MHz with my oscilloscope.

Nov 17, 9. Nov 17, 3. Adjacent rows of course have a rather high capacitance!! Select a forum Posted by t06afre in forum: Nov 17, 4.

Now I know that a crystal oscillator would be recommended for this, but I’d like to test my existing circuitry before I purchase datasgeet final parts I do not have any crystal oscillators. Hello, Did you read in the data sheet, that the speed of the inverters are dependend on the power supply?

There are ‘s that will do MHz, but they’re dataasheet of a custom microcontroller that’s for a specific use.

A ring of 3 gates will make an oscillator. 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. Your name or email address: Soft Robotic Cardiac Device Prevents Heart Failure Researchers have designed an implantable, soft-robotic cardiac device which fits around a failing heart and helps it restore normal blood flow. This also works with the TTL chips, wich will lead to higher frequencies,but smaller adjustment range, due to the voltage range of 4.

It used an input of 80 or MHz and there might have been a PLL to generate a lot more frequencies than you could merely by changing a divisor. Do you already have an account?

These will work to 85MHz. Yes, my password is: I initially had a little pin header for jumpers to select additional input capacitance for lower frequency ranges as shown in the upper-left corner of the drawing, but even with none of the jumpers installed, the tiny bit of capacitance between the top pins and ground was holding the maximum frequency down, so I cut the connection at point A marked with the “X”, near pin 9and also shorted out R1, bringing the max up to 73MHz.

Breadboards aren’t really good. For beginners, start at 1 or 2 MHz – you can 74s1124 away with long dataasheet and lots of stray capacitance and not worry about access times and propagation delays and still have everything work when you run this slow. However it also works well with small prototyping PCBs turned upside down copper at the top.
