Description and Introduction

Dual D-Type Positive-Edge-Triggered Flip-Flops With Clear and Preset The **SN74HC74DBR** is a dual D-type flip-flop integrated circuit manufactured by **Texas Instruments (TI)**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Type:** Dual D-Type Flip-Flop with Set and Reset  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current:** ±5.2 mA (at 4.5V supply)  
- **Propagation Delay:** 14 ns (typical at 5V)  
- **Input Capacitance:** 3.5 pF (typical)  
- **Package Type:** SSOP (DBR) - 14 pins  
- **Mounting Type:** Surface Mount  

### **Descriptions:**
- The **SN74HC74DBR** contains two independent D-type flip-flops with asynchronous **Set (S)** and **Reset (R)** inputs.  
- Each flip-flop features a **Data (D)** input, a **Clock (CLK)** input, and complementary outputs (**Q** and **Q̅**).  
- The device is designed for **high-speed** operation while maintaining low power consumption.  
- It is compatible with **TTL** logic levels and operates reliably across a **wide voltage range (2V to 6V)**.  

### **Features:**
- **Dual Flip-Flop:** Two independent D-type flip-flops in a single package.  
- **Asynchronous Set/Reset:** Direct control over outputs via **Set (S)** and **Reset (R)** pins.  
- **Edge-Triggered Clocking:** Data is transferred on the **positive edge** of the clock signal.  
- **Wide Operating Voltage:** Supports **2V to 6V** operation.  
- **High Noise Immunity:** CMOS technology provides robust performance.  
- **Low Power Consumption:** Typical **ICC** of **4 µA** (max) at 5V.  
- **Balanced Propagation Delays:** Ensures reliable synchronous operation.  

This information is strictly based on the manufacturer's datasheet for the **SN74HC74DBR** from Texas Instruments.

Application Scenarios & Design Considerations
