CD4017BM is a decade counter/divider integrated circuit that is used in digital logic/electronic circuits. It is ideal for counting and dividing binary coded decimal (BCD) numbers because it has 10 outputs, each representing one of the 10 digits in the BCD system. The chip contains two 4-bit ring counters and an output latch. The two counters are connected to form a decade counter while the output latch is used to access the outputs. It is also capable of generating pulse width modulation (PWM) signals.
CD4017BM has wide application fields that include clock distribution, frequency synthesis, PWM control and data acquisition. In clock distribution, the chip is used to divide a system clock frequency in order to generate signals at lower frequencies for logic or other important system clocks. Also, for clock applications, it can be used to provide a way of visualizing the activity of a system clock. In frequency synthesis, the chip is used to divide a high-frequency signal by specific values in order to generate related signals at lower frequencies. In data acquisition applications, it can be used to divide a fast data input rate in order to synchronize the data to a slower system speed. PWM applications are also a good application field for the chip. PWM signals generated by the chip can be used to control the speed and the direction of motors, dimmer the light intensity of lights, or for any other application that requires PWM control.
The working principle of CD4017BM is based on the two 4-bit binary counters that are part of its internal structure. Each counter is a ring counter and is made up of four flip-flop parts. Each flip-flop part consists of two cross-coupled NAND gates. As they are ring counters, they are connected in a loop. One of the counters is clocked at a frequency of twice the other counter and when this counter reaches its maximum value, it is reset and the other counter is incremented. The decade output pins can be used to access each of the 10 states of this counter, they can be connected directly to the output pins of either of the counters.
The output latch also plays an important role in the working principle of CD4017BM. The output latch is used to access the decade output pins when the counter is not in the reset state. It is made up of 4 D-type flip-flops, each of which can hold the logic state of one of the counter output pins for a period of time before it is updated by the counter. The outputs are then latched on the output pins and can be used until the counter is updated with the next value.
In general, the CD4017BM is a highly useful integrated circuit for creating counter and divider circuits. It provides a simple and effective way to create and access 10 output states and can be used for clock distribution, frequency synthesis, PWM control and data acquisition applications. With its 10 outputs and internal structure, it is the ideal component for these applications.
