Description and Introduction

3-STATE Octal D-Type Flip-Flop # **Introducing the MM74HCT574WM: A High-Performance Octal D-Type Flip-Flop**  

The **MM74HCT574WM** is a high-speed, low-power octal D-type flip-flop designed for applications requiring reliable data storage and transfer. Built with advanced HCT (High-Speed CMOS with TTL Compatibility) technology, this component ensures seamless integration into both CMOS and TTL-based systems while delivering superior performance.  

## **Key Features**  

- **Octal Edge-Triggered Flip-Flop** – The device features eight D-type flip-flops with a common clock (CP) and output enable (OE) control, making it ideal for bus-oriented applications.  
- **High-Speed Operation** – With propagation delays as low as 13 ns, the MM74HCT574WM ensures rapid data transfer, enhancing system efficiency.  
- **TTL-Compatible Inputs** – The inputs are fully compatible with TTL voltage levels, allowing for easy interfacing with legacy logic circuits.  
- **Low Power Consumption** – Utilizing CMOS technology, this flip-flop minimizes power dissipation, making it suitable for battery-operated and energy-sensitive designs.  
- **3-State Outputs** – The outputs feature a high-impedance state when disabled, preventing bus contention in multi-drop configurations.  
- **Wide Operating Voltage Range** – Supports a supply voltage range of 4.5V to 5.5V, ensuring stable performance across various operating conditions.  

## **Applications**  

The **MM74HCT574WM** is widely used in digital systems where buffering, data latching, or signal synchronization is required. Common applications include:  
- **Microprocessor and microcontroller interfacing**  
- **Data bus buffering and storage**  
- **Register banks and pipeline systems**  
- **Industrial control and automation**  

## **Reliable and Robust Design**  

Housed in a compact **SOIC-20 package**, the MM74HCT574WM offers excellent thermal and electrical performance, ensuring long-term reliability in demanding environments. Its robust construction and adherence to industry standards make it a preferred choice for engineers seeking a dependable flip-flop solution.  

For designers requiring high-speed, low-power data storage with TTL compatibility, the **MM74HCT574WM** delivers the performance and flexibility needed for modern digital systems.
