Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 20-SOIC package dimensions align with the target PCB footprint. Ensure the 1.65V to 3.6V supply voltage range matches the system power rails. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is needed for low-voltage digital systems. The 5.5V input tolerance allows interfacing with higher voltage logic sources without additional level shifting circuitry. Consider the 6.5ns propagation delay for timing-critical paths. The SOIC-20 package offers a compact solution for space-constrained designs requiring multiple buffered channels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC240A family of octal buffers and drivers. It shares functional similarities with other LVC series components but is distinct in its specific voltage range and package type. The 'SN74LVC240AN' variant typically denotes a tube-packaged version, whereas the 'SR' suffix indicates reel packaging. It serves as a standard interface component in mixed-voltage digital environments.
