Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RGYR corresponds to the 16-VQFN package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process specifications. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the official Texas Instruments datasheet for this specific revision.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require bidirectional translation between disparate voltage levels without external resistors. Consider the 16-VQFN package constraints regarding thermal dissipation and PCB layout space. Evaluate the 380 Mb/s data rate capability against your system's maximum clock speeds to ensure signal integrity is maintained under load conditions.
