Apr 5, 18, 3, Bill, if you figure out how to use the CD in a digital clock, please post your circuit! Aug 7, 4, Guess I’ll use the segments.

It would also be a good idea to add a small capacitor across the switch to debounce the switch. Frankly that datasheet that seems to be all that is available on the web sucks. How do we ignore the first C??

CMOS Decade Counter/Divider With Decoded 7-Segment Display Outputs And Display Enable

Maybe helpful, maybe not. Hello Bill, I have been looking around, but had no luck. Submitted by admin on 23 Dattasheet Still, I have to wonder what the heck they were thinking with the “Ungated C segment”.

I’ll start with a 99 minute counter, then add the mod that makes it 60 hours. Why does the clock input not work?

Whats the out put current per segment with fig 8 displayed? IMHO, this part was not designed to be used in a time clock, or if the designers were intending to include features to allow it to be used as such, they screwed up.

Hope I’m not being a pest. Device Function Package Mftr. Connected to the Ground low of the circuit, to enable clock pin.

Jul 10, I have a feeling I’m missing the obvious, something really, really obvious. There is some parasitic capacitance on the CMOS inputs. How would you manually reset the with a counter? With your SW1 arrangement the capacitance gets charged to 5 V when the switch is closed.

Unfortunately we do not have the information on how to do this as it does require some modification.

Questions Posted by Robin Mitchell in forum: They have a very high input impedance and a small capacitance. Ron, I googled this for around two days with no luck. I’ll leave it up to you which schematic to leave in the question. Okay one more then I’ll stop. The CD does not have outputs which allow this implementation.

Jul 8, Do you already have an account? This product is designed to run the common cathode displays but it can be set up to run a common anode. Seen it a couple days ago. Jul 7, 5. This is the carry over output pin; it produces a pulse after counting till 9.
