Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74AHC74 is a dual positive-edge-triggered D-type flip-flop from Texas Instruments (TI). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  

### **Specifications:**  
- **Technology:** Advanced High-Speed CMOS (AHC)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High Noise Immunity:** Typical CMOS levels  
- **Low Power Consumption:**  
  - ICC (Static Current) = 1 μA (Max) at 5.5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay (tpd):**  
  - 5.5 ns (Typ) at 5 V  
- **Output Drive Capability:** ±8 mA at 5 V  
- **Input Capacitance:** 3 pF (Typ)  
- **Package Options:** SOIC, PDIP, TSSOP  

### **Description:**  
The SN74AHC74 contains two independent D-type flip-flops with asynchronous clear (CLR) and preset (PRE) inputs. Each flip-flop features data (D) and clock (CLK) inputs, with outputs (Q and Q̅) that change state on the positive edge of the clock signal.  

### **Features:**  
- **Dual Flip-Flop:** Two independent D-type flip-flops in one package  
- **Edge-Triggered Clocking:** Positive-edge-triggered operation  
- **Asynchronous Inputs:** Direct clear (CLR) and preset (PRE) for immediate state control  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V  
- **Balanced Propagation Delays:** Ensures reliable timing performance  
- **Low Power Consumption:** Suitable for battery-operated devices  
- **Schmitt-Trigger Inputs:** Improved noise immunity  

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