Where to use CD IC The IC CD is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using Carry pin. We have 10 output pins ranging from Q0 to Q9, these pins can be connected to any load but we are using LEDs here as shown in the circuit below. This IC will increment the count from 0 to 9 Q0 to Q9 each time it senses a high pulse from the clock pin pin The output changes sequentially from Q0 to Q9 for every high pulse from the Clock pin, but this sequence can be interrupted by two pins. They are the Clock Enable pin 13 and Reset pin 15 pins.

I c4d also concerned that my chip may be damaged from static discharge, however I think that is unlikely and my problem is a wiring problem. There seems to be very little information on how to use this ic. Digital electronics Electronic design Electronics lists Integrated circuits.
The high input impedance fi of the VCO simplifies the design of low pass filters by permitting the designer a wide choice of resistorto-capacitor ratios. SameFrame pin-out refers to the arrangement ofdevices, you can use the SameFrame pin-out feature to migrate across an entire family of devices. Hex non-inverting buffer with tri-state outputs. Thank you for your interest in this question. I was unsure what to do with the carry in and carry out pins so I left them unconnected which may be part of my problem.
Each time power cd applied to the circuit the LEDs seem to turn on in a different order. Here is my extremely bad sketch of my circuit: I am trying to build a circuit that counts up to 15 or in binary using a ic and 4 LEDs as demonstrated in this video.
