Working Principles

The CD74HC4020M96 operates as a ripple counter, where each stage triggers the next stage upon reaching its maximum count. The clock input (CP) drives the counter, incrementing the count on each rising edge. The outputs (Q3-Q14) represent the binary count, with Q3 being the least significant bit and Q14 being the most significant bit. The master reset input (MR) resets the counter to zero when activated.

Detailed Application Field Plans

The CD74HC4020M96 finds applications in various fields, including:

1. Frequency Division: The counter can be used to divide an input frequency by a specific factor, enabling frequency scaling in electronic systems.
2. Time Measurement: By counting clock cycles, the IC can measure time intervals accurately, making it suitable for timers and clocks.
3. Event Counting: The counter can track the occurrence of events, such as button presses or sensor triggers, providing valuable data for monitoring and control systems.
