Procurement Notes

Verify the complete part number including the suffix ',118' to ensure correct packaging configuration. Confirm that the 56-TSSOP package matches your PCB footprint requirements. Check RoHS compliance status against current regulatory standards. Ensure the operating temperature range aligns with your system's thermal environment specifications before finalizing procurement.

Selection Notes

Select this component when a 20-bit parallel interface with registered output is required. Consider the 350 MHz speed limit for high-frequency applications. Verify compatibility with 3.3 V logic levels if interfacing with standard CMOS devices. Evaluate the 24 mA drive strength against load capacitance requirements to ensure signal integrity on the bus lines.
