Working Principles

The 74HC4024N,652 is a binary ripple counter that counts the number of clock pulses applied to its CP pin. It uses a built-in oscillator to generate the clock signal and has Schmitt-trigger inputs for improved noise immunity. The outputs represent the binary count from 0 to 7 (Q0 to Q6). When the maximum count is reached, the next clock pulse resets the counter to zero.

Detailed Application Field Plans

• Frequency division: The IC can be used to divide an input frequency by powers of 2, making it useful in frequency synthesizers and digital systems.
• Time delay generation: By connecting the appropriate output to the CP pin, the IC can generate precise time delays for various applications, such as controlling sequential operations.
• Event counting: The counter can be used to count events or pulses occurring at a specific rate, enabling applications like RPM measurement or event monitoring.

Detailed and Complete Alternative Models

• CD4024BE: Similar 7-stage binary ripple counter with buffered outputs, but operates at a wider voltage range (3 V to 18 V).
• MC14024B: Another 7-stage ripple counter with buffered outputs, offering improved noise margin and higher operating temperature range (-55°C to +125°C).
