IC 4017 – Pin Configuration & Application
Report item — opens in a new window or tab. Watch list is full.
Pin It is the output 8. It goes high when the counter reads 8 counts.
Pin It is the output 4. It goes high when the counter reads 4 counts. Pin It is the output 9.
It goes high when the counter reads 9 counts. Pin This is divided by 10 output which is used to cascade the IC with another counter so as to enable counting greater than the range supported by a single IC By cascading with another IC, we can count up to 20 numbers.
We can increase and increase the range of counting by cascading it with more and more IC s. Each additional cascaded IC will increase the counting range by However, it is not advisable to cascade more than 3 ICs as it may reduce the reliability of the count due to the occurrence glitches.
If you need a counting range more than twenty or thirty, I advise you to go with conventional procedure of using a binary counter followed by a corresponding decoder. Pin This pin is the disable pin. In normal mode of operation, this is connected to ground or logic LOW voltage.
If this pin is connected to logic HIGH voltage, then the circuit will stop receiving pulses and so it will not advance the count irrespective of number of pulses received from the clock.
Pin This pin is the clock input. This is the pin from where we need to give the input clock pulses to the IC in order to advance the count.
(hcf4017be) decade counter with 10 decoded outputs
The count advances on the rising edge of the clock. Pin This is the reset pin which should be kept LOW for normal operation. Pin This is the power supply Vcc pin.
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.
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 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.
Assembling this Circuit 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.It goes high when the counter reads 4 counts.
It has 16 pins and the functionality of each pin is explained as follows: Pin It is the output 5. On reaching "9" again returns to "0" and so on. Pin This pin is the disable pin. Similarly, if the reset pin is made high. Back to home page Return to top.
