Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74AC74DBR 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:** 7.5 ns (max) at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SSOP-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74AC74DBR features independent data (D), clock (CLK), set (SET), and clear (CLR) inputs for each flip-flop. The outputs (Q and Q̅) change state on the positive-going edge of the clock pulse.  

### **Features:**  
- **Dual Flip-Flop:** Two independent D-type flip-flops in one package.  
- **Edge-Triggered Clocking:** Data is transferred on the positive clock edge.  
- **Asynchronous Clear and Set Inputs:** Directly reset or set the outputs regardless of the clock.  
- **Wide Operating Voltage:** Supports 2 V to 6 V operation.  
- **Balanced Propagation Delays:** Ensures reliable performance in high-speed applications.  
- **Low Power Consumption:** Optimized for power-sensitive designs.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  

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