Description and Introduction

Octal D-Type Latch # **MM74HCT573: A Reliable Octal Transparent Latch for Digital Applications**  

The **MM74HCT573** is a high-performance octal transparent latch designed for digital systems requiring robust data storage and transfer. Built with advanced HCT (High-Speed CMOS with TTL Compatibility) technology, this component ensures fast operation while maintaining low power consumption—making it ideal for a wide range of applications, from industrial controls to consumer electronics.  

## **Key Features**  

- **Octal D-Type Latch:** The MM74HCT573 features eight transparent latches with 3-state outputs, allowing efficient data buffering and bus interfacing.  
- **High-Speed Operation:** With propagation delays as low as 13 ns, it supports high-speed digital circuits without compromising signal integrity.  
- **TTL Compatibility:** Inputs are TTL-compatible, ensuring seamless integration with both CMOS and TTL logic families.  
- **3-State Outputs:** The outputs can be placed in a high-impedance state, enabling bus-oriented applications and reducing bus contention.  
- **Wide Operating Voltage:** Supports a supply voltage range of **4.5V to 5.5V**, making it suitable for standard 5V logic systems.  
- **Low Power Consumption:** The HCT technology minimizes power dissipation, enhancing energy efficiency in battery-operated devices.  

## **Applications**  

The MM74HCT573 is widely used in:  
- **Microprocessor and microcontroller interfacing**  
- **Data storage and transfer systems**  
- **Memory address latching**  
- **Bus drivers and buffers**  
- **Industrial automation and control systems**  

Engineers and designers favor the MM74HCT573 for its reliability, speed, and ease of integration. Whether used in embedded systems, communication devices, or automation controls, this latch delivers consistent performance under demanding conditions.  

For applications requiring precise data retention and efficient signal management, the **MM74HCT573** remains a trusted choice in modern digital design.
