Description and Introduction

3-STATE Octal D-Type Edge-Triggered Flip-Flop # **MM74HC574WMX: High-Speed Octal D-Type Flip-Flop with 3-State Outputs**  

The **MM74HC574WMX** is a high-performance integrated circuit designed for digital logic applications requiring reliable data storage and transfer. As part of the 74HC family, this octal D-type flip-flop features edge-triggered operation and 3-state outputs, making it ideal for bus-oriented systems.  

## **Key Features**  

- **High-Speed Operation**: With propagation delays as low as 15 ns, the MM74HC574WMX ensures efficient data handling in high-frequency applications.  
- **3-State Outputs**: The outputs can be placed in a high-impedance state, allowing multiple devices to share a common bus without interference.  
- **Edge-Triggered Clocking**: Data is latched on the rising edge of the clock signal, ensuring precise timing and synchronization.  
- **Wide Operating Voltage**: Supports a 2V to 6V range, making it compatible with various logic levels.  
- **Low Power Consumption**: The CMOS technology ensures minimal power dissipation, even at high speeds.  

## **Applications**  

The MM74HC574WMX is widely used in digital systems where buffering, storage, or bus interfacing is required. Common applications include:  

- **Microprocessor and microcontroller interfacing**  
- **Data storage and transfer in communication systems**  
- **Address and data bus buffering**  
- **Register and pipeline designs**  

## **Reliability and Packaging**  

Housed in a compact **SOIC-20 package**, the MM74HC574WMX is designed for surface-mount assembly, ensuring space efficiency in modern PCB designs. Its robust construction and adherence to industry standards guarantee long-term reliability in demanding environments.  

For engineers seeking a dependable solution for digital data storage and bus management, the MM74HC574WMX offers a balance of speed, efficiency, and versatility. Its integration-friendly design makes it a preferred choice for high-performance computing and embedded systems.  

Whether used in industrial automation, telecommunications, or consumer electronics, this flip-flop IC delivers consistent performance while simplifying system architecture.
