Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official orderable addendum to confirm package type and temperature grade. Ensure the selected variant matches the required AEC-Q100 qualification level for the target automotive application. Cross-reference the datasheet revision history to confirm compatibility with current design specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver when designing networks requiring high-speed communication up to 8 Mbps with strict EMC requirements. The integrated VIO pin simplifies interface design by eliminating external level shifters for controllers operating between 1.7 V and 5.5 V. Consider the thermal characteristics and package size if space constraints are critical in the PCB layout.
