Logic circuits are important components of modern semiconductor technology. In order to fulfill the need for logic circuits that are reliable and efficient, the CD4018BE is one of the most popular choices. This high-speed static logic circuit can be applied to various parts of a computer, for example, performing counting operations, and making decisions. In this article, we will discuss the CD4018BE application field and working principle.

CD4018BE is a kind of pulse and delay binary counter, with a two-stage cascade divider. This static logic circuit is composed of 16 series-connected D-type flip-flops, with a count capability of 0-15. The clock input is from the first section, and the rest of the sections accept the output from the preceding one. Its input includes reset and four kinds of clock pulses, and its output includes 16 kinds of pulse signals and clock counting pulse signal. The internal circuit of the entire chip is composed of two separate circuits: a blank board and logic circuits.

Because of its good signal-to-noise ratio and low power consumption, CD4018BE can be widely used in the fields of frequency division (input clock FT signal), pulse signal conversion, selection signal generation, shift pulse generation, pulse width measurement, timing control and signal restoration in digital circuits.

In terms of working principle, the CD4018BE chip uses the "ripple-through" technique to count the rising edges of an input pulse signal. It receives the clock signal from the first output and transmits it to other clock outputs. When the reset is low, the count is reset to 0, otherwise it is reset to 15. The rising edges of clock pulses occur in the order of 1, 2, 3 and 4; when a pulse is present, the circuit starts counting and at the same time latches the current count on a high feedback line as a carry.* As each pulse moves through the counter, the previous output remain unchanged while the next output changes accordingly.

To sum up, the CD4018BE is a high-speed static logic circuit that can be widely used for counting, dividing, selection and other operations. It is composed of two separate circuits: a blank board and logic circuits. The working principle of the chip involves the use of the ripple through technique to count the rising edges of an input pulse signal. Moreover, the chip has excellent signal-to-noise ratio and low power consumption, making it an efficient tool for digital circuit applications.
