A CD74HCT4520M is a CMOS 16-bit counter/dividers with 4-bit counters, fully programmable divide ration, and asynchronous reset. It is a member of the high-speed CMOS logic families designed to operate from a single 5 V power supply. Manufactured using advanced CMOS technology, it is extremely versatile, high-performance, and low-power. It is designed to drive both static and dynamic logic. It is available in 16-pin DIP and SOIC surface mount packages.

The CD74HCT4520M is well-suited for a variety of applications including arithmetic, digital signal processing, and data conversion. In these applications, it is used for frequency division, divide by constant, pulse counters and dividers, edge detection, serial communications, and pattern recognition. It is also used in clock and timing synthesis, divider design, and frequency spectra splitting.

The CD74HCT4520M operates on a single 5V power supply and has two selectable output termination supply pins for both low and high logic levels. It has 16 bits of bi-directional data, providing a wide range of divide ratio and frequency selection. The device has two enable inputs, active-high and active-low, that determine the logic direction of the output signals. The pins are designed to be versatile and can be used in a wide variety of applications. Additionally, the device is designed to switch both high and low in order to reduce power consumption.

The CD74HCT4520M works by counting the number of clock cycles that have occurred since the last time the reset input became low. The reset input is asynchronous, so the CD74HCT4520M can be reset while the clock is still active. The divide ratio is determined by the number of clock cycles that occur between rising edges of the reset and the clock. When the divider reaches the pre-defined count, the CD74HCT4520M generates a pulse at the output. The output can either be a positive or negative pulse depending on the logic direction of the enable inputs. The divide ratio of the CD74HCT4520M can range from 1 to 16 bits.

In conclusion, the CD74HCT4520M is a versatile and reliable CMOS 16-bit counter/dividers with 4-bit counters, fully programmable divide ratio, and asynchronous reset. It is ideal for a variety of applications such as arithmetic, digital signal processing, and data conversion, and is available in basic 16-pin DIP or SOIC surface mount packages. The CD74HCT4520M works by counting the number of clock cycles that have occurred since the last time the reset input became low, and generates a pulse at the output when the divider reaches the predetermined count. The divide ratio of the CD74HCT4520M can range from 1 to 16 bits, depending on the number of clock cycles that occur between rising edges of the reset and the clock.
