You need a pull down resistor on you clock input if your switch is used to pull the cd0426be input high as it is in the schematic. I have a good example of a 12 Hour counter, but I still would like to figure out a 24 Hour version.

Maybe helpful, maybe not. Home Questions Tags Users Unanswered. I’ll leave it up to you which schematic to leave in the question.

Sunday, 27 November Question by: You have advance the project substantially, for which I thank you.

They simply have to generate a pulse of low voltage 0V and high voltage 5V. There is some parasitic capacitance on the CMOS inputs. Power output per pin 1Ma at 4.

Questions Posted by Robin Mitchell in forum: After that add the to convert it to a counter. We have 7 output pins naming from Out A to Out G which is directly connected to the 7-segment display. Apr 14, 7, You had omitted a ground connection on your LEDs. Would this be the same as you are saying? I don’t feel the need to reinvent the wheel in the slightest. At this time, the ones counter is at 9, so the combination instantly rolls over to 00 when the count hits This site uses cookies to deliver our services and provide a basic level of website functionality.

The CD does not allow reassigning counter states like I did here, because the 7 segment decodes are hard-wired, with the reset state of the counter decodes as zero. How would you manually reset the with a counter? There are three other output pins pin 5,4,14 which will be used only when the IC needs to be cascaded. Sorry- not much help.

The datasheet says there is a way, but neglects to mention how. Aug 7, 4, Connected to the Ground low of the circuit, to enable clock pin. Bill, if you figure out how to use catasheet CD in a digital clock, please post your circuit! Jul 8, Sign up or log in Sign up using Google.

How do we ignore the first C??

A part of the CMOS range. What is level on the Inhibit pin when you are applying the clock signal?

IF i keep clock on pos and toggle clock inhabit, it will start counting. Your name or email address: Jul 9, The count can be increased by simply giving a high clock pulse; also more than one digit can be created by cascading more than one CD IC.

If 24 hours is reached, cf4026be digits reset. This product is designed to run the common cathode displays but it can be set up to run a common anode. Note that in my CD implementation, the LSD reset state is called “1”, because that’s what a clock does. Alternatively use our Quotation page.
