Controllers Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Distribution availability is currently restricted or discontinued across major channels. Engineers must verify current stock status through authorized distributors before design finalization. Alternative sourcing strategies should be evaluated immediately due to potential supply chain limitations for this specific part number.

Controllers Selection Notes

Designers should prioritize this component when system requirements demand high data rates up to 24 Mb/s combined with significant buffering capacity. The integrated level shifters simplify board layout by eliminating external translation circuits. Verify that the target application environment remains within the specified -40°C to +85°C operating temperature range to ensure reliable performance throughout the product lifecycle.
