Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the RE4 suffix to ensure compliance with specific environmental standards and tape-and-reel packaging configurations. Confirm that the TSSOP-20 package dimensions match the target PCB footprint requirements. Cross-reference the datasheet revision history to ensure alignment with current manufacturing specifications and recommended operating conditions before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with three-state capability under low-voltage operation. The LVC series offers improved performance over standard LVC devices regarding speed and power consumption. Ensure the application voltage remains within the 1.65 V to 3.6 V range to maintain specified timing parameters. Consider the thermal characteristics and package size constraints associated with the TSSOP-20 form factor during layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC240A family of octal buffers and line drivers. It shares functional similarities with other members of the LVC logic family but is distinguished by its specific pinout and three-state output configuration. The RE4 suffix indicates a specific manufacturing variant often associated with lead-free compliance and reel packaging, differentiating it from tube-packaged equivalents like the SN74LVC240ADW.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVC240ADWR serves as a compatible alternative offering identical logical functionality and pinout compatibility. Verify that the replacement package type meets the assembly requirements, as the ADWR variant may utilize different packaging formats compared to the PWRE4 version.
