Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging variant rather than tube packaging. Confirm RoHS compliance status and check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when open-collector outputs are required for wired-AND configurations or level shifting applications. Ensure the driving circuitry can handle the sink current capabilities inherent to open-collector designs. Verify that the 8-bit width aligns with the target bus architecture requirements.
