I still think it isn’t obvious, however it looks like I’ll get there. Maybe you can get something from it.

They simply have to generate a pulse of low voltage 0V and high voltage 5V. The four different types of cookies are: Your name or email address: I’m going to measure LED currents, I am still not confident of the lack of resistors.

Google kept referring me back to my own articles. Jul 7, 5. Sorry- not much help. Decade counter with 7-segment display driver 3 to 18VDC supply voltage ns propagation delay 0. Unfortunately we do not have the information on how to do this as it does require some modification. I wrote the author of the wrist watch article a thanks, he mentioned having different old data book that explained how it was done. Maybe a scheme for reset after 6 clock pulses.

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. I’ll defiantly use Rapid online again, and my college will continue to use this service.


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

Ron, I googled this for around two days with no luck. Hope I’m not being a pest. Alternatively use our Quotation page.

Cd4062be need a pull down resistor on you clock input if your switch is used to pull the clock input high as it is in the schematic. I have included a simulation using CDs that counts from 1 through 12 and then repeats.

Divide by 10 CO. The switch is xatasheet going to be a timer, for now its just me moving a wire from pos to neg. This is an output pin which will be rarely used when division is required.

He does this by delaying the carry out of the tens counter by one clock cycle using a D FF, which makes the output of the FF go high when the tens count gets to 6. IF i keep clock on pos and toggle clock inhabit, it will start counting. Note how the use of the GND symbol eliminates much wiring and enables instant identification of grounded points in the circuit. I was hoping to use the clock inhabit to stop the counting of the clock input. Jul 7, 7.

Jul 6, 1. One single IC can be used to count form zero 0 to nine 9 directly on a Common Cathode type 7-segment display. At this time, the ones counter dtaasheet at 9, so the combination instantly rolls over to 00 when the count hits Jul 10, Power output per pin 1Ma at 4. Sunday, 27 November Question by: At least now I can help other people who datasheer have similar problems.


Jul 7, 8. I’ll try this, then I’ll try the other. A part of the CMOS range.

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. We have 7 output pins naming from Out A to Out G which is directly connected to the 7-segment display. Jul 7, 2. TL — Programmable Reference Voltage.

Guess I’ll use the segments. As a result the chip was put straight to use without any flaws dataseet my project. Jul 9, Okay one more then I’ll stop. If 24 hours is reached, hours digits reset.

The ground pin should be connected to ground of circuit. Why does the clock input not work? It would also be a good idea to add a small darasheet across the switch to debounce the switch. Mar 24, 21, 2, URL here At the very bottom. I have a good example of a 12 Hour counter, but I still would like to figure out a 24 Hour version. The Reset pin pin 15 is used to reset the count back to zero when made high.

I’m wondering if there is a sadistic sense of humor by a TI engineer way back when. You May Also Datasheeet
