Description and Introduction

3-STATE Octal D-Type Latch # **MM74HC573MTCX: A High-Performance Octal Transparent Latch for Digital Applications**  

The **MM74HC573MTCX** is a high-speed CMOS octal transparent latch designed for efficient data storage and transfer in digital systems. Featuring eight D-type latches with 3-state outputs, this component is ideal for applications requiring buffered data storage, bus interfacing, and signal isolation.  

Built with advanced silicon-gate CMOS technology, the MM74HC573MTCX offers low power consumption while maintaining high noise immunity and robust performance. Its 20-pin TSSOP package ensures compact integration, making it suitable for space-constrained designs. With a wide operating voltage range of **2V to 6V**, this latch is compatible with both TTL and CMOS logic levels, enhancing its versatility across various digital circuits.  

Key features include **transparent latching**, allowing data to pass through when the latch enable (LE) input is high, and **3-state outputs**, which enable high-impedance disconnection for bus-oriented systems. The output enable (OE) input provides additional control, allowing designers to manage data flow efficiently.  

The MM74HC573MTCX is widely used in **microprocessor systems, memory addressing, data routing, and I/O expansion**. Its fast propagation delay and high drive capability ensure reliable performance in high-speed digital environments.  

For engineers seeking a dependable, high-performance latch solution, the **MM74HC573MTCX** delivers precision, efficiency, and compatibility, making it a preferred choice in modern digital designs.

Application Scenarios & Design Considerations

3-STATE Octal D-Type Latch

Alternative Part Number

  • SN74HC573ADWR --: Pin-compatible octal D-type transparent latch with 3-state outputs in the same HC logic family and SOIC-wide package, widely available and directly interchangeable.
  • MC74HC573ADWR2G --: Equivalent HC573 octal latch with 3-state outputs in SOIC-20W, same function and pinout, good second-source option.
  • CD74HC573M96 --: HC573 octal transparent latch with 3-state outputs in SOIC-20, functionally and pin-compatible alternative with broad availability.
