Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ATPYG against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding pin pitch and footprint dimensions. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal wide-bus interface is required with low propagation delay characteristics typical of the FCT family. Consider the 20-pin SOIC package constraints for PCB space limitations. Verify that the system power supply remains stable within the specified 4.75V to 5.25V range to ensure reliable logic level translation and signal integrity across all eight channels.
