Working Principles

The HEF4520BT,652 is a synchronous binary counter that utilizes flip-flops to store and propagate binary information. The built-in oscillator generates clock pulses, which are fed into the CP pin. On each rising edge of the clock pulse, the counter increments by one. The Master Reset input can be used to reset the counter to zero, while the Terminal Count output indicates when the maximum count value is reached. The Reset Counter output provides a synchronous reset signal.

Detailed Application Field Plans

• Frequency division in digital circuits
• Timekeeping and clock generation
• Event counting and timing applications
• Industrial automation and control systems
