Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the ABT logic series meets the system's speed and power requirements. Ensure the SOIC-20 footprint matches the PCB design constraints. Check RoHS compliance documentation for environmental regulations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bidirectional data path is needed with high drive capability. The ABT series offers a balance of speed and power efficiency compared to standard CMOS logic. Consider the 4.8 ns propagation delay for timing-critical applications. The 64 mA sink current supports heavy capacitive loads on the bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT620 series of octal bus transceivers. It is functionally similar to the SN74ABT620DW but differs in packaging configuration. The DWR suffix indicates reel packaging, suitable for surface-mount technology (SMT) production lines, whereas other suffixes may indicate tube packaging.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74ABT620DW for tube-packaged equivalents. Other compatible parts in the ABT family may offer similar electrical characteristics but require verification of pinout and package dimensions.
