Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74AC240DWR2G --: Octal buffer/line driver with 3-state outputs, same AC logic family and 20-pin SOIC wide-body package, direct functional and pin-compatible replacement.
  • 74AC240SCX --: Equivalent octal inverting buffer/line driver in AC family with 3-state outputs, SOIC-20 package, widely available and pin-compatible.
  • CD74AC240M96 --: Same manufacturer AC-family octal buffer/line driver with 3-state outputs in SOIC-20, electrically compatible though different series prefix.
  • 74AC240SC --: Same AC-series octal inverting buffer/line driver with 3-state outputs in SOIC-20, matching pinout and drive characteristics for drop-in replacement.
  • CD74AC240M --: TI AC-family octal buffer/line driver with 3-state outputs, same logic function and voltage range; SOIC package variant offers a close second-source option within the same family.
