Clock Enable EN. This is an input which when made high will hold the count at the current state. The counting happens when this clock pulse goes high , this pin is normally connected to timer or other uC to produce a pulse. As the name suggests this pin resets the count back to 1.

Complete Technical Details can be found at the CD datasheet given at the end of this page. 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.

This is commonly used for Led chasers and other logical output projects, so if you are looking for an sequential decoded counting IC that can count up to 10 then this IC will be your right choice. 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.

Most of us are more comfortable with 1, 2, 3, 4… rather than , , , We mean to say that we will need a decimal coded output in many cases rather than a raw binary output. We have many counter ICs available but most of them produce binary data as an output.

IC 4017 – Pin Configuration & Application

We will again need to process that output by using decoders or any other circuitry to make it usable for our application in most of the cases. Let us now introduce you a new IC named IC It is a CMOS decade counter cum decoder circuit which can work out of the box for most of our low range counting applications. It can count from zero to ten and its outputs are decoded. This saves a lot of board space and time required to build our circuits when our application demands using a counter followed by a decoder IC.

This IC also simplifies the design and makes debugging easy.

It has 16 pins and the functionality of each pin is explained as follows:. This IC is very useful and also user friendly. To use the IC, just connect it according the specifications described above in the pin configuration and give the pulses you need to count to the pin of the IC. Then you can collect the outputs at the output pins.

In this, we have eight LEDs which glow one after the other to form a circling effect. My intention in publishing this circuit is not just to make some art work with electronics but also to illustrate the working principle and circuit design using IC in astable mode, counter and to explain the related concepts.

The IC will operate in astable mode with a frequency of 14Hz. The IC in the circuit is used as a clock pulse generator to provide input clock pulses to the counter IC The IC in the circuit operates at a frequency of 14Hz, which means that it produces about 14 clock pulses every second to the IC Now we shall analyze what happens at IC IC is a digital counter plus decoder circuit.

Whenever a clock pulse is received at the clock input of IC counter, the counter increments the count and activates the corresponding output PIN.

This circuit can be housed on a general purpose PCB or a stripboard and the LEDs in the circuit are to be arranged in a circular shape. Not just a circle! You can experiment with any other shapes and designs and get a beautiful circling effect for your own shape. What Other shapes can you try? Any of course, but here are a few suggestions.

You can try to construct the first letter of your name with this circling effect. I made this circuit a few years ago in the shape of my first letter D but I have de soldered it some time ago when I was badly in need of LEDs for some other project.

A timer IC1 is used in astable mode i.
