Procurement Notes

This component is classified as End-of-Life (EOL) by the manufacturer. Production has been discontinued, and no new inventory is available through standard channels. Designers must verify current stock availability with authorized distributors or consider alternative sources carefully. Procurement should focus on last-time buy opportunities if immediate replacement is not feasible. Verify part authenticity due to potential market fluctuations in obsolete components.

Selection Notes

Select this component only for legacy designs requiring exact specification matching. Evaluate system compatibility with existing clock architectures before implementation. Consider the impact of discontinuation on long-term supply chain stability. Review datasheet parameters for voltage levels and output drive strengths. Ensure that alternative solutions meet all functional requirements if migration is planned.
