CD74HCT4520MT is a popular dual 4-bit synchronous up-counter that belongs to the family of Logic – Counters, Dividers. The 74HC/HCT4520 can be easily integrated into a range of digital systems, offering an efficient solution to count and divide digital signals. It also provides improved noise immunity, besides other advantages.

The 74HC/HCT4520 provides two separate 4-bit up-counters, both of which can be reset via the MR (Master Reset) pin. The counters are designed to be cascaded such that the Q3 output of one chip becomes the CP (Clock Pulse) input of the other, amplifying the output and making it easier to manage the design.

The CD74HCT4520MT has a common clock input (CP1) and two 4-bit outputs with separate synchronous reset inputs (RES1). The first 4-bit output (Q0 to Q3) is directly related to the clock and reset inputs, allowing synchronous counting or dividing by 2. The second 4-bit output (Q4 to Q7) is related to the first 4-bit output, allowing asynchronous counting or the division of count rhythms by 4.

The CD74HCT4520MT has a wide range of applications. It can be used for duty cycle modulation, frequency division, frequency counting and much more. In addition, it can be used for the construction of DTL, TTL and CMOS-compatible clocks. The 74HC/HCT4520 provides superior noise immunity, making it ideal for applications where noise levels may be high.

The working principle of the 74HC/HCT4520MT is relatively simple. The chip contains two 4-bit up-counters connected in series, each having its own clock input and reset input. The clock input is tied to a clock signal, while the reset input is tied to the MR (master reset) pin. When the clock signal is asserted, the counter works as an up-counter, counting up from 0 to 15. When the reset signal is asserted, the counter is reset and the output is set to 0.

The 74HC/HCT4520MT can count and divide digital signals, making it a useful component for a variety of digital systems. Its superior noise immunity and wide range of applications make it an ideal choice for engineers looking for a reliable and efficient solution to count and divide digital signals.
