Working Principles

The CD74HC4020M96E4 is a binary ripple counter that counts the number of clock pulses applied to its input pin. It consists of 14 flip-flops connected in a cascading manner, where each flip-flop divides the frequency by 2. The built-in oscillator generates the clock signal, eliminating the need for an external clock source. The counter advances by one on each rising edge of the clock signal. The active low reset function allows synchronous resetting of the counter to zero.

Detailed Application Field Plans

• Frequency division: The CD74HC4020M96E4 can be used to divide the frequency of an input signal by a factor of 2^14 (16,384). This is useful in applications such as clock generation, frequency synthesis, and digital communication systems.
• Time measurement: By connecting an external clock signal to the input pin, the counter can be used to measure time intervals. The number of clock pulses counted represents the elapsed time.
• Event counting: The CD74HC4020M96E4 can be used to count events occurring at regular intervals. This is useful in applications such as traffic monitoring, production line control, and event timing.
