Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'REP' indicates a restricted distribution or enhanced quality screening variant as defined by Texas Instruments. Confirm RoHS compliance status through official documentation before procurement. Ensure the UQFN-16 footprint matches the design layout requirements precisely. Check for automotive qualification if the application demands AEC-Q100 standards, as standard commercial parts may differ.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 1.2V to 3.6V logic families requiring high-speed performance in compact spaces. The UQFN package offers a small form factor suitable for dense PCB layouts. Consider the 3-state output capability for bus sharing applications. Verify that the required data rate does not exceed 380 Mb/s and that the operating temperature range aligns with environmental conditions.
