74HC4020DB is an iconic chip produced by Logic - Counters, Dividers. Its application field and working principle involve a complex concept. In order to understand 74HC4020DB clearly and use it cleverly, we are going to learn its basic application field, working principle and also its implementation.

Application Field of 74HC4020DB

As a member of the 74HC family of CMOS logic ICs, 74HC4020DB is a 12-stage ripple counter with a decoder output and has a wide application in many fields. First of all, this chip is used in frequency divisions and clock signals due to its 12-stage ripple counter capability. In practice, it is used in products including various digital clocks, digital clocks for quartz watches and other frequency-divided products in quartz watches. Secondly, it is usedat systems where a long difference frequency is required, such as communication systems. Finally,it is used as a divider or counter in computer or industrial control equipment.

Working Principle of 74HC4020DB

The working principle of 74HC4020DB can be divided into two parts: the ripple-counter part and the decoder part. The ripple-counter part includes the two RCOs (Reset-Clock Output) and the twelve CLKs (Clock Input) as the basis of its counter operation. Each CLK will be advan
