Procurement Notes

Verify the specific suffix (e.g., APAG) against the manufacturer's current datasheet to ensure pinout and electrical specifications match your design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for any product change notices or end-of-life announcements from Renesas Electronics Corporation to avoid supply chain disruptions.

Selection Notes

Select this component when designing systems requiring 20-bit parallel data buffering with mixed-voltage compatibility. Ensure the PCB layout accommodates the 56-pin TSSOP package dimensions. Verify that the system power supply remains stable within the 2.7V to 3.6V range to maintain optimal switching performance and noise margins.
