Functional Features

• Decade Counter: The HCF4028M013TR can count from 0 to 9 in a cyclic manner.
• Divide-by-N Function: It can divide the input clock signal by a factor of N, where N is the count value.
• Master Reset: The MR pin allows resetting the counter to zero.
• Carry Output: The CARRY OUT pin provides a carry signal when the counter reaches its maximum count value.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient counting and dividing of signals. - Low power consumption makes it suitable for battery-powered devices. - Compact SOIC-16 package enables easy integration into electronic circuits.

Disadvantages: - Limited counting range from 0 to 9, which may not be sufficient for certain applications. - Propagation delay of 60ns may introduce timing issues in high-frequency applications.

Working Principles

The HCF4028M013TR operates based on digital logic circuitry. It uses flip-flops and combinational logic to count and divide input clock signals. The BCD inputs determine the initial count value, and the clock input triggers the counting process. When the counter reaches its maximum count value, a carry signal is generated. The master reset input allows resetting the counter to zero.

Detailed Application Field Plans

The HCF4028M013TR can be used in various applications, including:

1. Frequency Dividers: It can divide the frequency of an input signal by a factor of 10, making it useful in frequency synthesis circuits.
2. Digital Counters: The decade counter functionality allows for precise counting in digital systems, such as event counters or timers.
3. Sequential Logic Circuits: It can be used as a building block in sequential logic circuits, enabling complex operations based on counting and dividing signals.

Alternative Models

1. CD4028BE: This is a similar decade counter/divider IC from Texas Instruments, available in DIP-16 package.
2. MC14028B: Another alternative from ON Semiconductor, offering similar functionality in a different package.

These alternative models can be considered based on specific requirements and availability.
