Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74AHC74DR is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits per Element:** 1  
- **Number of Elements:** 2  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Level Input Voltage (Min):** 2 V  
- **Low-Level Input Voltage (Max):** 0.8 V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Output Type:** Push-Pull  
- **Package / Case:** SOIC-14  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 10.5 ns (typical at 5 V)  
- **Current - Quiescent (Max):** 2 µA  

### **Descriptions:**  
The SN74AHC74DR features two independent D-type flip-flops with individual clear (CLR) and preset (PRE) inputs. Each flip-flop stores one bit of data and transfers it to the output on the rising edge of the clock (CLK) signal.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** 2 µA (Max)  
- **High Noise Immunity**  
- **Balanced Propagation Delays**  
- **Direct Clear and Preset Inputs**  
- **ESD Protection Exceeds 2000 V (Per JESD 22)**  
- **Latch-Up Performance Exceeds 250 mA (Per JESD 78)**  

This device is commonly used in applications requiring data storage, synchronization, or signal delay.
