Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with 3.3V power supplies and check for obsolescence status prior to procurement. Confirm that the required switching capacity matches the 2,048 x 2,048 channel limit defined in the datasheet.

Selection Notes

Select this component when a high-density, non-blocking TSI solution is required for telecommunications environments. It is suitable for designs needing automatic protocol detection for ST-BUS/GCI and flexible delay management across multiple data streams. Consider the 3.3V operating voltage and industrial temperature range requirements during system planning.
