This transceiver is commonly used in data communication systems, networking equipment, and other applications requiring bidirectional data transfer.

Application Scenarios & Design Considerations

25-Ohm Octal Bus Transceivers With 3-State Outputs

Alternative Part Number

  • 74ABT245DWR --: Same ABT-family octal bus transceiver with 3-state outputs in the same wide SOIC-24 package; a close functional substitute when the integrated bus-hold and termination features of the ABTH25245 are not required.
  • CY74FCT245TQCT --: FCT-family octal bus transceiver with 3-state outputs offering comparable speed and drive in a similar wide-body package; a practical alternative from a different series.
  • 74ACT245SC --: ACT-family octal bus transceiver with 3-state outputs in a wide SOIC-24 package; widely available and functionally similar for general bidirectional bus buffering.
