CD4024BM

CD4024BM is a CMOS logic device manufactured by Harris semiconductor. It is a ripple-carry binary counter, composed of four master-slave flip flops, with each stage having its own data input and clock input. The counter contains four binary stages, with the count q0 through q3 providing output for each stage of count. It is suitable for use in various applications that require counters with various counting sequence, such as synchronous counters, up-down counters or up/down modulo-n counters.

Application field

CD4024BM is mainly used in applications where high speed, low power consumption, and ease of use are important. It is often used in onboard counters and arithmetic functions in a variety of systems. It is used in automotive and industrial control systems, where it is used to count impulses and signals in a very fast and accurate way. It is also used in communication systems, where it performs time division multiplexing and pulse width modulation. Other more specialized applications include speakers, motors, medical equipment, etc.

Working principle

The CD4024BM uses a three stage ripple-carry design, with each binary stage having its own data input and clock input. Each stage of the ripple-carry counter is driven by a separate data and clock input. The data input is a digital signal that is used to determine the state of the counter. The clock input triggers the counter to shift its state based on the data input. The output of the first stage is fed back to the data input of the next stage, and so on. When the last stage, q3, reaches the value of “1”, it triggers the counter to reset, and the count begins again from the first stage.

In addition to the three main stages, the CD4024BM is also equipped with a clear input, SET input, and an enable input. The clear input will reset the counter to its default state, while the SET input will preset the counter to a predetermined value, and the enable input is used to control the counter, i.e. to start, pause, or stop the counter.

Conclusion

The CD4024BM is a versatile counter with a range of applications and working principles. It is designed to be a low-power, high-speed CMOS device, making it perfect for various applications that require counters with various counting sequences. Its clear input and set input allow it to be used in a variety of ways and makes it an ideal choice for many counter applications.
