Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and sourcing may require verification through authorized distributors or secondary market suppliers. Buyers should confirm the specific revision status and ensure compliance with RoHS directives before procurement. Lead times are not guaranteed due to the discontinued status.

Selection Notes

Select this part for applications requiring 18-bit wide synchronous FIFO buffering at moderate speeds. Verify that the system voltage aligns with the 4.5V to 5.5V operating range. Ensure the PCB layout accommodates the TQFP-64 package dimensions. Consider the EOL status when designing for long-term production viability.
