Description and Introduction

Dual D-Type Positive-Edge-Triggered Flip-Flops With Clear and Preset The SN74HCT74PWLE is a dual positive-edge-triggered D-type flip-flop with clear and preset features, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Circuits:** 2  
- **Output Type:** Push-Pull  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -4mA  
- **Low-Level Output Current (IOL):** 4mA  
- **Propagation Delay Time (tpd):** 25ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-14  

### **Descriptions:**  
- The SN74HCT74PWLE is a high-speed CMOS logic device with TTL-compatible inputs.  
- Each flip-flop has independent data, clock, set, and reset inputs.  
- It features buffered outputs for improved noise immunity.  

### **Features:**  
- **Dual Flip-Flops:** Two independent D-type flip-flops in a single package.  
- **Edge-Triggered:** Data is transferred on the positive clock edge.  
- **Asynchronous Clear & Preset:** Directly sets or resets outputs regardless of clock state.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **TTL-Compatible Inputs:** Works with TTL logic levels.  
- **High Noise Immunity:** Improved noise resistance due to buffered outputs.  

This device is commonly used in digital systems for data storage, synchronization, and signal delay applications.
