Description and Introduction

Dual D-type Positive-Edge-Triggered Flip-Flops With Preset And C The SN54S74J is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Series:** SN54S74J (Military-grade, high-reliability)  
- **Technology:** Schottky TTL (S-Series)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** Ceramic Dual-In-Line (J-Lead)  
- **Number of Flip-Flops:** 2 (Dual)  
- **Trigger Type:** Positive-edge-triggered  
- **Clock Input:** Independent for each flip-flop  
- **Output Type:** Standard TTL (Totem-Pole)  
- **Propagation Delay (Typical):** 7 ns (at 5V, 25°C)  
- **Power Dissipation:** ~80 mW per flip-flop  

### **Descriptions:**
- The SN54S74J is a high-speed, dual D-type flip-flop with individual data (D), clock (CLK), preset (PRE), and clear (CLR) inputs.  
- It is designed for military and aerospace applications, offering high reliability and performance under extreme conditions.  
- Each flip-flop stores a single bit of data, transferring the input (D) to the output (Q) on the rising edge of the clock signal.  
- Asynchronous preset (PRE) and clear (CLR) inputs override the clock and set the outputs independently.  

### **Features:**
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Schottky TTL Technology:** Provides improved speed and power efficiency.  
- **Dual Flip-Flop Configuration:** Two independent flip-flops in a single package.  
- **Edge-Triggered Clocking:** Ensures reliable data capture on the rising clock edge.  
- **Asynchronous Clear and Preset:** Allows immediate output control.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.  
- **Military-Grade Reliability:** Meets stringent MIL-STD-883 standards.
