Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs 20-SOIC -40 to 85 The SN74HC244DWRE4 is a high-speed CMOS logic octal buffer and line driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Buffer/Line Driver  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 2V to 6V  
- **High-Level Output Current:** -7.8mA  
- **Low-Level Output Current:** 7.8mA  
- **Propagation Delay:** 13ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-20 (DW)  

### **Descriptions:**  
- Designed for bus-oriented applications  
- Non-inverting outputs

This device is commonly used in digital systems requiring buffering and signal driving.

Application Scenarios & Design Considerations

Octal Buffers And Line Drivers With 3-State Outputs 20-SOIC -40 to 85

Alternative Part Number

  • MC74HC244ADWG --: Same 74HC244 octal buffer/driver function in a 20-pin SOIC wide-body package, pin-compatible and widely available.
  • 74HC244D,653 --: Equivalent 74HC244 octal buffer with 3-state outputs in SO20 package, direct functional and footprint replacement.
  • CD74HC244M96 --: Same HC-family octal buffer in SOIC-20 from an alternate TI series, electrically compatible with the original.
