Description and Introduction

LOW POWER SCHOTTKY The SN74LS74A is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Circuits:** 2  
- **Flip-Flop Type:** D-Type  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Propagation Delay Time (Max):** 40 ns  
- **Current - Output High, Low:** 400µA, 8mA  
- **Package / Case:** 14-Pin PDIP, SOIC  

### **Descriptions:**  
The SN74LS74A is a dual D-type flip-flop with individual clear (CLR) and preset (PRE) inputs, as well as complementary outputs (Q and Q̅). It is designed for edge-triggered operation, where data is transferred to the output on the rising edge of the clock pulse.  

### **Features:**  
- **Dual Flip-Flops:** Contains two independent D-type flip-flops.  
- **Edge-Triggered Operation:** Responds to the positive clock transition.  
- **Asynchronous Clear and Preset Inputs:** Allows immediate setting or resetting of outputs.  
- **Wide Operating Voltage:** Compatible with standard TTL levels.  
- **Complementary Outputs:** Provides both Q and Q̅ for each flip-flop.  
- **Low Power Consumption:** Optimized for power efficiency in the LS family.  

For detailed electrical characteristics and timing diagrams, refer to the official TI datasheet.
