Description and Introduction

Octal Buffers/Drivers With 3-State Outputs The SN74AHC244NSR is a non-inverting octal buffer and line driver from Texas Instruments (TI). Here are the key specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Description:**  
The SN74AHC244NSR is an octal buffer and line driver designed with 3-state outputs. It is part of TI's AHC (Advanced High-Speed CMOS) logic family, offering high-speed operation while maintaining low power consumption.  

### **Key Features:**  
- **Logic Type:** Octal Buffer/Line Driver (Non-Inverting)  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Speed Operation:** 8.5 ns max propagation delay at 5 V  
- **Low Power Consumption:**  
  - ICC (Static Current) typically 1 µA  
  - Low dynamic power dissipation  
- **High Output Drive:** ±24 mA at 5 V  
- **ESD Protection:**  
  - 2000 V Human-Body Model (HBM)  
  - 1000 V Charged-Device Model (CDM)  
- **Package:** SOIC-20 (NSR)  

### **Applications:**  
- Bus buffering and signal driving  
- Memory address driving  
- General-purpose logic interfacing  

This device is designed for high-performance digital systems requiring reliable signal buffering and driving capabilities.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74VHC244DTR2G --: Octal buffer/line driver with 3-state outputs in the same VHC speed family, TSSOP package, direct functional equivalent to the SN74AHC244.
  • 74AHC244PW,118 --: AHC-family octal buffer/line driver with 3-state outputs, TSSOP-20 package, same logic function and comparable drive strength.
  • 74VHC244MTCX --: VHC octal buffer/line driver with 3-state outputs in TSSOP-20, pin-compatible and functionally interchangeable with the AHC244.
  • TC74VHC244FT --: VHC octal buffer/line driver with 3-state outputs in a TSSOP-type package, suitable drop-in functional replacement for the AHC244.
