**Descriptions:**  
The SN74LV244ARGYR is an octal buffer and line driver designed for 2 V to 5.5 V VCC operation. It features 3-state outputs for bus-oriented applications and is suitable for driving high-capacitance loads.  

**Features:**  
- Supports mixed-mode voltage operation  
- Typical output skew < 1 ns  
- Low power consumption (ICC = 10 µA max)  
- I/O ports tolerate up to 5.5 V  
- Latch-up performance exceeds 250 mA per JESD 17  
- ESD protection exceeds JESD 22 (2000-V Human-Body Model)  

This device is commonly used in digital systems for signal buffering and line driving applications.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • 74LVC244APW,118 --: Octal buffer/line driver with 3-state outputs in the same LVC logic family; functionally equivalent to the SN74LV244A and widely available in TSSOP.
  • MC74LCX244DTR2G --: Octal buffer/line driver with 3-state outputs, low-voltage CMOS logic, direct functional replacement with similar drive and speed characteristics.
  • 74LV244AT20-13 --: Octal buffer/line driver in the LV family offering equivalent logic function and 3-state outputs as a cost-effective alternative.
