### **Descriptions:**  
The SN74ALVC244RGYR is an octal buffer and line driver designed for 1.65V to 3.6V VCC operation. It features non-inverting outputs and 3-state outputs for bus-oriented applications. The device is optimized for low-voltage, high-speed operation while maintaining low power consumption.  

### **Features:**  
- **Wide Operating Voltage Range:** 1.65V to 3.6V  
- **High-Speed Operation:** 2.7ns max propagation delay  
- **3-State Outputs:** Allows connection to a bus system  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **Balanced Output Drive:** ±24mA at 3V  
- **ESD Protection:** Exceeds 2000V per JESD 22  
- **Latch-Up Performance:** Exceeds 250mA per JESD 78  
- **Packaging:** 20-pin VQFN (RGY)  

This device is commonly used in digital systems requiring buffering and signal driving in low-voltage applications.

Application Scenarios & Design Considerations

Octal Buffer/Driver With 3-State OUtputs

Alternative Part Number

  • 74ALVC244PW,118 --: Same ALVC 244 octal buffer function with equivalent 3.3V speed and drive, offered in TSSOP package as a close functional replacement.
  • 74ALVC244MTCX --: Pin-compatible octal buffer/line driver in the ALVC family with similar propagation delay and drive current, suitable for direct substitution.
  • 74ALVC244BQ,115 --: ALVC octal buffer in a smaller DHVQFN package, electrically equivalent for 3.3V logic buffering when board space allows a package change.
