Description and Introduction

Dual D-Type Positive-Edge-Triggered Flip-Flops With Clear and Preset The SN74HC74DR is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Series:** 74HC  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Circuits:** 2  
- **Output Type:** Complementary  
- **Trigger Type:** Positive Edge  
- **Supply Voltage (VCC):** 2V to 6V  
- **High-Level Output Current (IOH):** -5.2 mA  
- **Low-Level Output Current (IOL):** 5.2 mA  
- **Propagation Delay Time (tpd):** 20 ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74HC74DR features two independent D-type flip-flops with asynchronous clear (CLR) and preset (PRE) inputs. Data is transferred to the output (Q) on the positive edge of the clock (CLK) pulse. The device operates over a wide voltage range (2V to 6V) and is designed for high-speed CMOS logic applications.

### **Features:**  
- **Dual Flip-Flop:** Two independent D-type flip-flops in a single package.  
- **Edge-Triggered:** Positive-edge clocking for synchronous operation.  
- **Asynchronous Inputs:** Direct clear (CLR) and preset (PRE) override clocked operations.  
- **Wide Operating Voltage:** Supports 2V to 6V supply range.  
- **High Noise Immunity:** Typical of CMOS technology.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Balanced Propagation Delays:** Ensures reliable performance in sequential logic circuits.  
- **SOIC-14 Package:** Compact surface-mount design for space-constrained applications.  

This information is based on Texas Instruments' official documentation for the SN74HC74DR.
