CD74HC4017PWRG4

Introduction

CD74HC4017PWRG4 is a high-speed CMOS Divider/Counter logic circuit. It is a type of widely used logic integrated circuit which enables to divide or count the input clock pulses by either 7 or 10 depending on the divide ratio selection made by the user. Apart from being used as a divider, this device can be used as a wide range of sequential logic components such as oscillators, dividers, synchronizers, and decoders.

Application Field

The CD74HC4017PWRG4 is an ideal circuit for numerous applications. These include digital instrumentation, clock synchronization, frequency synthesis, and digital frequency synthesis. It can be used in motor control systems, industrial, medical, aerospace and military applications. In addition, it can be used in fields such as digital control systems, control and process engineering, robotics, security systems, and telecommunications.

Working Principle

The operation of the CD74HC4017PWRG4 starts with the input of the clock pulse. This pulse is the source of the timing information and is used to carry out the division or counting sequence. The input clock pulse has to be maintained at a steady frequency in order to ensure correct operation. When the divide ratio is selected to be 7 or 10, the internal counter slices the inputs clock pulse into 9 or 12 output pulses, each pulse representing one increment of the counter. The output of the divider is thus equivalent to the desired number of cycles of the input clock source.

Performances

The CD74HC4017PWRG4 operates from a single 5V supply and has a maximum operating frequency of 10MHz. Its operating temperature range is between -55°C and +125°C. It has an LVH (Space Radiation) package rating of 28. The device is rated for normal operation of up to 6.5V. The power dissipation for the device is 150mA.

Conclusion

The CD74HC4017PWRG4 is a high speed CMOS Logic Divider/Counter, capable of dividing its input clock source into a total of either 9 or 12 evenly divided output pulses depending on the selectable divide ratio. This provides a versatile and reliable divide-by-7 or divide-by-10 capability. In addition to providing functionality of a divider circuit, it can also be used as a wide range of sequential logic components in various industrial, aerospace and military applications. In order to ensure proper operation, the input clock pulse must be of a steady frequency.
