Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74AC74DR is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Circuits:** 2  
- **Output Type:** Complementary  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 2 V to 6 V  
- **High-Level Output Current:** -24 mA  
- **Low-Level Output Current:** 24 mA  
- **Propagation Delay Time:** 9.5 ns (typical) at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74AC74DR features independent data (D) inputs, clock (CLK) inputs, set (SET), and clear (CLR) inputs for each flip-flop.  
- It operates on a wide voltage range (2 V to 6 V) and provides high-speed performance with low power consumption.  
- The outputs change state on the positive-going edge of the clock pulse.  

### **Features:**  
- **Dual Flip-Flop:** Contains two independent D-type flip-flops.  
- **Edge-Triggered Clocking:** Responds to the positive clock edge.  
- **Asynchronous Clear and Preset:** Directly sets or resets outputs regardless of clock state.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **Wide Operating Voltage:** Supports 2 V to 6 V operation.  
- **High Noise Immunity:** Typical of AC logic family.  
- **Low Power Consumption:** Optimized for battery-powered applications.  

This device is commonly used in data storage, synchronization, and sequential logic applications.
