Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive classification. Confirm the 'G4' indicates lead-free and RoHS compliance. Ensure the SOIC-14 package matches your PCB footprint requirements. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing design integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive reliability standards are mandatory. The three-state output allows multiple devices to share a common bus without interference. Verify that the 1.65 V minimum supply voltage meets your system's low-power requirements. Consider the 7 ns propagation delay for timing-critical automotive communication protocols.
