Thanks for these videos! I appreciate your format. 1st reviewing the data sheet, then going over a few applications for the IC, and ending it with a demo. Really cool! Plus, suggesting a few alternative IC’s towards the end really helps illustrate the different use cases and applications. Thanks again!
I have to say, I love this jellybean series! It is also nice if you can get recommendations on parts because as a beginner, there are sooo many CMOS chips, it can be overwhelming to choose one. So jellybean parts are a nice entry! Thank you so much!
I also like the 4046 and the 4040 very much and used them for many test circuits. With the HC4040 you can make a nice demonstration. The sum of the output spectrum of the chip in operation, taken from the supply for instance, is very interesting. It has all the frequencies with their harmonics and they all have an amplitude proportional to their frequency. With such a characteristic picture on the spectrum analyzer, you can immediately recognize the binary counter inside an LNB where the local oscillator is divided down to be stabilized by a lower frequency quartz in a phased locked loop.
The 74HC4040 seems cool enough just to make that nice pattern on the scope : ) Thanks for the videos. Lately, I'm fancying SN74LVC245AN bus transceivers. They are about $1. Lady Ada did a page about them. As you likely know, the older versions of them were used in buses of 8-bit computers, such as the Commodore 64 as seen on Adrian's Digial Basement, and the Coco3 (just buffering the CPU from the cartridge slot). The SN74LS245 is at the heart of Ben Eater's breadboard computer's bus. They also clean up edges nicely, well, they are bus transceivers, after all. For some reason these bus transceivers chips really conjure my imagination, for say--making an Arduino with bus slots. I think that an old-fashioned bus made from these is about as fast as I2C. It would be daft yet fun to experiment using a shift register to enable them, though a mistake with several enables might be smokey. Also, they like you to pull-up or down the unused input pins, so they don't float. I wonder if an bus pull-down resistor/pack would work. Oddly, I am trying them for level shifting from 3.3 to 5v from a Teensy 4.1, for stepper drivers because I want to do level shifting on the cheap, on 20 channels. Still, one must heed the current per pin, and package to make sure the draw is not too high. They file it under "bus contention." I wish the current output was a little higher for driving optocouplers without a driver transistor/MOSFET, though lately, I am giving up my beloved NEC PS2501 's anyway, for something with a Schmidt trigger in it, but I don't know what part yet. Still on this project, I am going right out of the box with the bus transceivers and up to 8 feet of cable, with 5v. Should be an interesting experiment. One of my favorites parts isn't a chip, but IRL640A - 18 AMP 200-Volt Logic-Level MOSFET, which runs fine from an 5-volt Arduino with a small current limiting resistor in it along the gate. It's Rgs is a little high for modern specs at .18 ohms, but at its price point of $1.63m, they have been a staple of mine. A resistor pulling down gate to ground, like a 10k, keeps lets the shut off in a timely manner. Some MOSFETS will remain on, unless the gate is...um...drained. LOL! For coils and relays, and to actually for everything, I always use an external diode in flyback configuration. Yes, I know there's one in there, but still. My old electric scooter controller died blew several MOSFETs at once, because the flyback diodes were poor. I have seen a MOSFET with a Zener diode in it, which might work well for static, but perhaps not for an inductive spike from a solenoid coil.
4060 is cool because you can drive those clock pins with a 32.768 kHz crystal. Check out the entire series, 4020, 4040, 4060. A very neat series of binary ripple counters.
The 4060 itself doesn't have any timing components. It just divides down the clock frequency. If you use it with external components to create an oscillator, then it's no better than the accuracy and stability of the external components. The RC circuit in the video will be okay if you don't need accuracy, but you can obviously do much better by using a crystal to set the frequency.
The accuracy comes from the clock source. You can use a Xtal as the oscillator on this 4060 part. Beware if using the Cmos 4060 parts as the max toggle frequencies of the Cmos 4000 series is pretty low (around 2MHz max). For this part it’s 8MHz and the 74HC part is a bit better than that, but these Logic families are pretty slow so you can’t use a 30MHz input and get away with it.
The counting part was pretty much implied 😄. Was more wondering about the "ripple" part in the devices name and how this chip is best used in comparison to other counters. (Since you are making a video about it...)
@@Peter_A1466 the ripple may or may not be a problem in your circuit. just need to be aware it is not synchronous. the IC is great for dividing down a clock. If used for something like an address counter, be sure the address load signal occurs once the 4040 ripple has settled.
@@Peter_A1466 I must admit I was left thinking. I can see the uses of a /10 and /16 but why /12, what specific uses does that solve? Having mentioned you have to be aware of something that is a bit more in depth, all I know now is, I still don't know why that is. Quite clearly IMSAI has a much greater in depth and broader knowledge of the subject than I do, which is why I watch the videos. No disrespect intended.
@@IMSAIGuy Thank you! I like your component videos, but sometimes I find it hard to see the true worth of a part if it's totally new (or a new variety) to me.

The 4060 is super useful…
As you can use its osc pins as a Xtal oscillator and divide down…
Only gotcha is the missing output stage 👍🏻
It struck me that it might go nicely with a 32768 Hz watch crystal. You'd get 2 Hz at the last stage.
Good stuff. Must informative.

It would have been nice, if you had shown how to hook up the circuit.
Would be interesting to see if the scope can pick up the ripple, vs a synchronous counter
Can you do a mixer? Sa612 or something
the 612 is used in the nanovna: th-cam.com/video/yGKWBpgN8PU/w-d-xo.html
I recommend the cmos cookbook by Don Lancaster
Cool. How accurate and cosistant is the timing on the 4060 ?

Another chip to look at? 4066
coming soon
Still no idea what it does and what you've used it for...
it counts. I used it to count
