This device is commonly used in digital systems requiring buffering and signal driving.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74VHC244DWR2G --: Octal buffer/line driver with 3-state outputs in the same SOIC-20 wide package and similar AHC-speed logic family, direct functional equivalent.
  • 74AHC244D,118 --: Same 74AHC244 octal buffer function in SO-20 package with matching supply voltage range and drive strength, pin-compatible drop-in.
  • SN74AHCT244DW --: Same package and pinout octal buffer from the AHCT family with TTL-compatible inputs, usable when input thresholds allow, though the series differs from AHC.
