Description and Introduction

Dual D-Type Positive-Edge-Triggered Flip-Flops With Preset And Clear The SN74S74N is a dual D-type positive-edge-triggered flip-flop integrated circuit (IC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Circuits:** 2  
- **Trigger Type:** Positive Edge  
- **Output Type:** Standard  
- **Supply Voltage (VCC):** 4.75V to 5.25V (Nominal 5V)  
- **High-Level Output Current (IOH):** -1 mA  
- **Low-Level Output Current (IOL):** 20 mA  
- **Propagation Delay Time (tpd):** 10 ns (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-14 (Plastic Dual In-line Package)  

### **Descriptions and Features:**  
- **Dual Flip-Flop:** Contains two independent D-type flip-flops with individual data (D), clock (CLK), preset (PRE), and clear (CLR) inputs.  
- **Edge-Triggered Operation:** Data is transferred to the output on the positive (rising) edge of the clock pulse.  
- **Asynchronous Clear and Preset:** Directly sets or resets outputs regardless of clock state.  
- **TTL-Compatible Inputs:** Compatible with standard TTL logic levels.  
- **Wide Operating Voltage Range:** Designed for 5V operation.  
- **High-Speed Performance:** Suitable for high-speed digital applications.  

This IC is commonly used in digital systems for data storage, synchronization, and sequential logic applications.

Application Scenarios & Design Considerations

Dual D-Type Positive-Edge-Triggered Flip-Flops With Preset And Clear

Alternative Part Number

  • DM74S74N --: Direct pin-compatible dual D flip-flop in the same 74S TTL family, widely available as a drop-in replacement.
  • MC74S74N --: Equivalent dual D-type flip-flop with identical logic function and DIP-14 pinout, suitable for direct substitution.
  • N74S74N --: Same 74S-series dual D flip-flop in DIP-14 package, functionally and pin compatible with the original.
