Description and Introduction

12-Stage Binary Counter # **MM74HC4040N: A High-Speed Binary Counter for Precision Timing Applications**  

The **MM74HC4040N** is a high-performance 12-stage binary ripple counter designed for precision timing and frequency division applications. Built with advanced CMOS technology, this integrated circuit (IC) delivers reliable operation while maintaining low power consumption, making it an excellent choice for digital systems requiring accurate clock division.  

## **Key Features**  

- **12-Bit Binary Counter:** The MM74HC4040N features a 12-stage ripple-carry counter, allowing frequency division by up to 4096 (2^12). This makes it ideal for applications such as clock generation, event counting, and timing control.  
- **High-Speed Operation:** With propagation delays as low as 16 ns, the IC ensures efficient performance in high-frequency circuits.  
- **Wide Operating Voltage Range:** Supports a supply voltage range of 2V to 6V, providing flexibility for both 3.3V and 5V systems.  
- **Low Power Consumption:** The HC (High-Speed CMOS) technology minimizes power dissipation, enhancing energy efficiency in battery-operated devices.  
- **Asynchronous Reset:** A master reset (MR) pin allows immediate clearing of the counter, ensuring precise control over timing sequences.  

## **Applications**  

The MM74HC4040N is widely used in digital electronics, including:  
- **Frequency Dividers** – Reduces clock signals to lower frequencies for timing circuits.  
- **Digital Clocks** – Provides accurate timekeeping in microcontroller-based systems.  
- **Event Counters** – Tracks pulses in industrial automation and instrumentation.  
- **Waveform Generation** – Assists in creating precise timing signals for communication systems.  

## **Reliability and Compatibility**  

As part of the 74HC logic family, the MM74HC4040N ensures compatibility with TTL inputs while offering improved noise immunity and reduced power consumption. Its robust design makes it suitable for industrial, automotive, and consumer electronics applications where stability and precision are critical.  

For engineers and designers seeking a dependable binary counter with high-speed performance and low power requirements, the **MM74HC4040N** stands as a proven solution for advanced digital timing applications.

Application Scenarios & Design Considerations

12-Stage Binary Counter

Alternative Part Number

  • CD74HC4040E --: Same 12-stage binary ripple counter function with HC logic family, DIP-16 package, and pin-compatible pinout; widely available and direct functional drop-in.
  • SN74HC4040N --: Equivalent 12-stage ripple-carry binary counter in 16-pin DIP with matching HC speed and voltage characteristics; different naming series makes it easy to distinguish.
  • MC74HC4040ANG --: HC-series 12-stage binary counter in DIP-16 with compatible logic levels and pinout; alternate source for the same counter function.
