The CD doesn’t count up.

Those are exactly the answers I needed. Do you cd4040be datasheet to pull the input up or down with a resistor? However, the can count very quickly, and will count the various momentary cd4040be datasheet that occur when the switch contacts close. Some are more clear than others. There was an error while thanking. datasheeg

They count an incoming frequency over a period cd4040be datasheet time cd4040be datasheet output the original frequency divided down with flip flops. To know check the datasheet and look for a minimum clock speed.

And also do you put a negative voltage onto the pins to activate it, or a positive? Getting a little beyond your questions: Why doesn’t daatsheet just say positive and cd4040be datasheet Thank you soo much! Did you miss your activation email?

For example, you can pull it up with a resistor, then pull it down cd4040be datasheet your switch to ground.

What does that mean? Hello, this cd4040be datasheet the first time I have posted on this forum, am I in the right place for asking questions? Or can cd040be simply attach a push button to it and it will count cd4040be datasheet one every time you push it, same goes for the reset pin can you just put a switch on it?

No pulling up or down is for inputs only.

Thanks for helping us to improve our site

By low I mean ground or near to it, and the same voltage as on pin 8 Vss 1d – Depends on your debouncing circuit a bit. But as a maxim, a digital input shall never be left floating. For example DRAM will “forget” what you put cr4040be it’s memory after a few milliseconds unless you cd40440be refresh cd4040be datasheet.

Please login or register. Some leave important information off them, cd4040be datasheet is I think because “everyone knows these parts. Paul Moir Frequent Contributor Posts: Hopefully I haven’t posted cd4040be datasheet the wrong spot.

All I ever needed to know was Vcc and Vdd were the positive terminals while Vee and Vss get connected to negative or ground. Any help would be very helpful, thank you in advance. To count up you probably want something more like a decade counter or Johnson counter, etc. It can be high for a month, low for a cd4040be datasheet and it’ll count it. My question is about the use of a cde chip, a while ago I saw one of Dave’s videos about his DIY clock which used one of these chips, am I correct in cd4040ve that this chip will count up cd4040be datasheet the Q pins in binary when a signal is cd4040be datasheet in the clock pin.

March 25, Many early microprocessors cd4040be datasheet worked this way, and it was a big deal for battery operated applications when processors that you could clock xd4040be to zero came out. This is normally how digital gates and flip flops work.

The only time you can make an exception to the floating input rule is that you know for a fact it’s fine and why. If you just connected it to a switch, cd4040be datasheet other side of which was connected to ground, then when the switch was open the input would be left floating.
