Working Principle

The CD4520BEG4 is based on two four-stage synchronous up/down counters. Its two up/down counter stages consist of four D-type flip-flops and an up/down decoder. The output stages of the up/down counters are connected to a counter which is connected to the input of the up/down decoder. The output of the up/down decoder is connected to the CLK input of the D-type flip-flops, which provides clock pulses for the two up/down counters. The output of the two up/down counters are then connected to the input of the counter, allowing it to count clocking pulses and increment or decrement the count.

The CD4520BEG4 also contains presets that allow users to customize the count up to 16 stages. These presets are connected to the control terminals of the counter, and can be set to either preset or an open condition. If the preset condition is selected, the count output will remain at the preset value until reset. The input to the up/down decoder is also connected to the reset terminals if user requires reset.

The CD4520BEG4 uses an internal 10KHz clock source, with an output frequency of up to 24MHz. For precise timing and control, the component is offered with a wide range of timing selections and features, ideal for precise clock timing. Lastly, its synchronous output stages ensure that precise frequency divisions and controlled timing are achieved, providing reliable clock signals.

In summary, the CD4520BEG4 is an ideal logic component for applications requiring precise clock timing. Its two four-stage synchronous up/down counters, preset terminals and output stages provide a wide range of timing applications ranging from data timing, counting and synchronization. Its precision timing and low power consumption further add to its design flexibility, making it an ideal choice for timing related applications.
