- **Wide Operating Voltage Range:** 1.65V to 3.6V  
- **Supports Mixed-Mode Voltage Operation**  
- **Bus-Hold on Data Inputs (Eliminates Need for External Pull-up/Pull-down Resistors)**  
- **Ioff Supports Partial-Power-Down Mode Operation**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  
- **ESD Protection Exceeds JESD 22 (2000-V Human-Body Model, 1000-V Charged-Device Model)**  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Octal Buffer/Driver With 3-State Outputs

Alternative Part Number

  • 74LVC244APW,118 --: Same octal buffer/line driver function with 3.3V LVC-family logic and TSSOP package; Nexperia is a major logic supplier and this is a direct functional equivalent.
  • MC74LCX244ADTR2G --: Octal buffer/line driver in the LCX low-voltage CMOS family with 5V-tolerant inputs, matching the LVCH244A's core function and TSSOP footprint.
  • 74LVC244APW-Q100,118 --: Automotive-qualified octal buffer in TSSOP with LVC-family 3.3V operation and 5V-tolerant inputs, suitable as a robust drop-in functional replacement.
  • 74LVC244APW --: Same octal buffer/line driver function with 3.3V LVC-family logic and TSSOP package; pin-compatible and widely available.
  • 74LVC244APW-Q100 --: Automotive-qualified octal buffer in TSSOP-20 with LVC-level inputs; suitable drop-in when higher reliability grade is acceptable.
