Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs 20-SOIC -40 to 85 The SN74HCT244DWRG4 is a high-speed CMOS logic octal buffer and line driver manufactured by Texas Instruments (TI). Here are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Logic Type:** Octal Buffer/Line Driver  
- **Technology:** HCT (High-Speed CMOS, TTL-compatible inputs)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage (Max):** 5.5V  
- **Output Current (High/Low):** ±6mA  
- **Propagation Delay:** 13ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-20 (DWR)  

### **Descriptions:**  
- The SN74HCT244DWRG4 is a non-inverting octal buffer and line driver designed for bus-oriented applications.  
- It features 3-state outputs for bus interfacing and reduces the need for external pull-up/pull-down resistors.  
- Compatible with TTL logic levels, making it suitable for mixed-voltage systems.  

### **Features:**  
- **Octal Buffer/Driver with 3-State Outputs**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **Balanced Propagation Delays**  
- **Low Power Consumption (HCT technology)**  
- **ESD Protection Exceeds 2000V (HBM)**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  

This device is commonly used in digital systems for signal buffering, level shifting, and bus driving applications.
