#### **Descriptions:**  
The SN74LVT244BDBR is an octal buffer and line driver designed for low-voltage (3.3V) applications. It features 3-state outputs for bus-oriented applications and provides high drive capability while maintaining low power consumption.  

#### **Features:**  
- **3.3V Operation:** Optimized for 3.3V systems.  
- **High Drive Outputs:** Supports up to 64 mA sink/source current.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  
- **Flow-Through Pinout:** Simplifies PCB layout.  

This device is commonly used in data communication, networking, and digital systems requiring buffering and signal driving.

Application Scenarios & Design Considerations

3.3-V ABT Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • 74LVT244APW,118 --: Same LVT octal buffer/line driver function in TSSOP package, widely available and pin-compatible in most designs.
  • 74LVTH244AMTCX --: LVTH octal buffer with 3-state outputs, similar speed and drive, TSSOP package, good drop-in alternative.
  • 74LVT244BQ,115 --: Equivalent LVT octal buffer/line driver in DHVQFN package, suitable when a smaller footprint is acceptable.
  • 74LVT244APW --: Same LVT octal buffer function in TSSOP package, widely available and pin-compatible with similar drive strength.
  • MC74LVT244ADTR2 --: Equivalent LVT octal buffer/line driver with 3-state outputs, drop-in functional replacement in TSSOP.
  • 74LVTH244AMTC --: LVTH octal buffer with bus-hold, similar speed and drive, suitable substitute when bus-hold is acceptable.
