Description and Introduction

Dual D Flip-Flop # **Introducing the MM54C74J: A Reliable Dual D-Type Flip-Flop for Precision Applications**  

The MM54C74J is a high-performance dual D-type flip-flop designed to meet the demands of modern digital systems. Built with precision and reliability in mind, this CMOS integrated circuit offers low power consumption, high noise immunity, and stable operation across a wide range of applications.  

Featuring independent data inputs, clock inputs, and direct clear and preset controls, the MM54C74J provides flexibility in sequential logic design. Each flip-flop operates independently, making it ideal for applications requiring synchronized data storage, frequency division, or state control. With a typical propagation delay of just 60ns at 5V, this component ensures efficient signal processing in time-critical circuits.  

The MM54C74J is designed to operate over a broad voltage range (3V to 18V), making it compatible with both TTL and CMOS logic levels. Its robust construction ensures minimal power dissipation, even in high-speed switching environments, while its high noise immunity reduces susceptibility to signal interference—critical for industrial and automotive applications.  

Key features include:  
- **Dual D-type flip-flops** with independent control inputs  
- **Direct clear and preset** for asynchronous initialization  
- **Wide operating voltage range** (3V to 18V)  
- **Low power consumption** for energy-efficient designs  
- **High noise immunity** for reliable performance in noisy environments  

Whether used in data registers, counters, or control circuits, the MM54C74J delivers consistent performance and durability. Its compact design and industry-standard pinout ensure easy integration into existing systems, making it a preferred choice for engineers seeking a dependable flip-flop solution.  

For applications requiring precision timing, signal synchronization, or sequential logic control, the MM54C74J stands as a trusted component in digital circuit design.

Application Scenarios & Design Considerations

Dual D Flip-Flop

Alternative Part Number

  • CD54HC74F --: Dual D flip-flop with preset and clear in the same 54-series military grade family, HC CMOS logic, direct functional equivalent to the C74.
  • SN54HC74J --: Military temperature range dual D-type flip-flop with clear and preset, pin-compatible CMOS replacement for the MM54C74J.
  • MC54HC74J --: 54-series high-speed CMOS dual D flip-flop with preset and clear, functionally and pin compatible alternative from a different manufacturer series.
  • CD54HC74F3A --: Dual D flip-flop in the same 54-series military temperature range with HC CMOS technology, a direct functional replacement for the C74 logic function in a ceramic package.
  • SNJ54HC74J --: Military-grade dual D-type flip-flop with clear and preset, same J ceramic DIP footprint and function, using the faster HC family instead of the older C family.
  • MC54HC74AJ --: Second-source 54-series dual D flip-flop in a ceramic DIP, pin-compatible and functionally equivalent, offering supply diversity from a different manufacturer.
