This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74VHCT240ADTR2G --: Octal buffer/line driver with 3-state outputs in the same AHCT/VHCT speed family, TSSOP-20 package, pin-compatible and widely available as a TI alternative.
  • 74AHCT240PW,118 --: Direct functional equivalent octal inverting buffer/line driver with 3-state outputs, AHCT logic family, TSSOP-20 package, drop-in replacement.
  • SN74AHCT244PWR --: Same AHCT family and TSSOP-20 package but non-inverting; suitable when polarity change is acceptable and offers an easy same-vendor sourcing option.
