Description and Introduction

OCTAL BUS BUFFER WITH 3 STATE OUTPUTS (NON INVERTED) The **M74HCT244RM13TR** is a high-speed CMOS octal buffer/line driver with 3-state outputs, manufactured by **STMicroelectronics (ST)**.  

### **Key Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL-compatible)  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** 3-State (Tri-State)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage Range:** 0V to VCC  
- **High-Level Output Current:** -6mA  
- **Low-Level Output Current:** 6mA  
- **Propagation Delay:** Typically 13ns at 5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-20 (Surface Mount)  

### **Descriptions and Features:**  
- Designed for bus-oriented applications requiring buffering and signal driving.  
- **3-State Outputs:** Allows multiple devices to share a common bus without interference.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  
- **High Noise Immunity:** CMOS technology provides robust noise resistance.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **ESD Protection:** Enhanced electrostatic discharge protection.  

This device is commonly used in digital systems for signal buffering, data transmission, and interfacing between different logic levels.
