Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • 74ALS240AD --: Same 74ALS240 octal inverting buffer function in SOIC-20, pin-compatible with the TI device and widely available from a different vendor.
  • DM74ALS240AWM --: Equivalent ALS240 octal buffer/line driver in SOIC-20 with matching logic and drive characteristics, offering a second-source option.
  • SN74ALS240AN --: Same TI ALS240 function in a PDIP-20 package, suitable when through-hole mounting is acceptable instead of the SOIC wide-body package.
