Description and Introduction

Dual Positive-Edge-Triggered D-Type Flip-Flops With Clear and Preset The SN74ACT74PW is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Speed Operation:** 5.5 ns (max) at 5V  
- **Low Power Consumption:** 8 µA (max) at 5V  
- **Input Voltage Levels:**  
  - **High-Level Input Voltage (VIH):** 2V (min)  
  - **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **Output Drive Capability:** ±24 mA at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-14 (PW)  

### **Descriptions:**  
- Contains two independent D-type flip-flops with **asynchronous clear (CLR)** and **preset (PRE)** inputs.  
- Data (D) input changes are clocked on the **positive edge** of the clock (CLK) pulse.  
- Outputs (Q and Q̅) reflect the stored data when both CLR and PRE are inactive (HIGH).  

### **Features:**  
- **Edge-Triggered Flip-Flop:** Ensures stable data transfer on clock rising edge.  
- **Asynchronous Clear and Preset:** Allows immediate control over output states.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **Wide Operating Voltage:** Supports standard 5V logic levels.  
- **Schmitt-Trigger Inputs:** Improves noise immunity.  

This device is commonly used in **data synchronization, registers, and control logic applications**.
