Description and Introduction

DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP The SN54LS73J is a dual negative-edge-triggered J-K flip-flop with clear, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Technology:** TTL (Transistor-Transistor Logic)  
- **Number of Circuits:** 2 (Dual Flip-Flop)  
- **Trigger Type:** Negative-Edge  
- **Function:** J-K Flip-Flop with Clear  
- **Supply Voltage (VCC):** 4.75V to 5.25V (Standard 5V operation)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Pin Count:** 14  

### **Descriptions and Features:**  
- **Dual Flip-Flop:** Contains two independent J-K flip-flops in a single IC.  
- **Negative-Edge Triggered:** Changes state on the falling edge of the clock pulse.  
- **Clear Function:** Each flip-flop has an asynchronous clear input (active LOW).  
- **High-Speed Operation:** Typical propagation delay of 15 ns.  
- **Low Power Consumption:** Optimized for reduced power usage compared to standard TTL.  
- **Military-Grade:** Designed for harsh environments with extended temperature range.  
- **Wide Compatibility:** Works with other TTL logic families.  

This device is commonly used in digital systems for data storage, counters, and control applications.

Application Scenarios & Design Considerations

DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP

Alternative Part Number

  • DM54LS73J --: Same 54LS73 dual J-K flip-flop function in a J-lead ceramic DIP package, pin-compatible and directly interchangeable.
  • M54LS73J --: Equivalent 54LS73 dual J-K flip-flop in ceramic DIP, matching logic family, pinout, and temperature range.
  • 54LS73AJ --: TI 54LS73 dual J-K flip-flop in ceramic J package, same LS TTL function and pinout, suitable as a drop-in replacement.
  • DM74LS73N --: Dual J-K flip-flop with clear in the same LS logic family, functionally equivalent and widely available from TI.
  • MC74LS73N --: Pin-compatible dual J-K flip-flop with clear, same 74LS series, suitable drop-in replacement for most designs.
  • SN74LS73N --: Commercial temperature grade version of the same dual J-K flip-flop, identical function and pinout for non-military applications.
