Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74AC74NSR is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Technology:** Advanced CMOS (AC)  
- **Supply Voltage Range:** 2 V to 6 V  
- **High-Level Input Voltage (Min):** 2 V  
- **Low-Level Input Voltage (Max):** 0.8 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Drive Capability:** ±24 mA  
- **Propagation Delay Time (Max):** 9.5 ns at 5 V  
- **Package Type:** SOIC (14-pin)  
- **Logic Type:** D-Type Flip-Flop  

### **Descriptions:**  
- The SN74AC74NSR consists of two independent D-type flip-flops with individual clear (CLR) and preset (PRE) inputs.  
- Data is transferred to the output (Q) on the positive edge of the clock (CLK) pulse.  
- Asynchronous clear and preset inputs override the clock and data inputs.  

### **Features:**  
- **Dual Flip-Flops:** Two independent flip-flops in a single package.  
- **Edge-Triggered Clocking:** Positive-edge-triggered for synchronous operation.  
- **Asynchronous Inputs:** Clear (CLR) and preset (PRE) for immediate state control.  
- **Wide Operating Voltage:** Supports 2 V to 6 V operation.  
- **High Noise Immunity:** Typical of CMOS technology.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **Balanced Propagation Delays:** Ensures reliable timing performance.  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • MC74AC74DTR2G --: Dual D-type flip-flop with async preset/clear in the same AC logic family, offered in a SOIC-14 package as a direct functional replacement for the NSR SOIC variant.
  • 74AC74SCX --: Equivalent 74AC74 dual flip-flop in SOIC-14, widely available and pin-compatible with the original NSR package.
  • CD74AC74M96 --: TI's own AC-family dual D flip-flop in SOIC-14, same logic function and supply range, useful when staying within the TI portfolio is preferred.
