- **Low-Level Output Current:** 24mA  

### **Descriptions:**  
The SN74ALS244CNSR is an octal buffer and line driver designed for 5V operation. It features 3-state outputs, allowing multiple devices to share a common bus without interference. It is commonly used in bus-oriented applications where buffering and signal driving are required.  

### **Features:**  
- **Octal Buffer/Line Driver with 3-State Outputs**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **High-Current Outputs for Driving Bus Lines**  
- **Low Power Consumption (ALS Series)**  
- **ESD Protection Exceeds 2000V**  
- **Balanced Propagation Delays**  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Octal Buffers/Line Drivers with 3-State Outputs

Alternative Part Number

  • MC74ACT244DWR2G --: Octal buffer/line driver with 3-state outputs in a wide SOIC-20 package, functionally equivalent to the SN74ALS244 and widely available.
  • 74ACT244SCX --: Same logic family function (octal buffer with 3-state outputs) in SOIC-20, direct functional replacement with compatible pinout.
  • CD74ACT244M96 --: Octal non-inverting buffer/line driver with 3-state outputs, pin-compatible SOIC-20 alternative suitable for the same application.
