This part is RoHS non-compliant, which means it uses lead-based solder terminations. For designs that must meet RoHS exemption criteria (e.g., certain aerospace, medical, or high-reliability applications), this is acceptable. For commercial or consumer products requiring lead-free assembly, a RoHS-compliant alternate should be sourced. The non-compliant status is a BOM gate — verify your project's environmental compliance requirements before committing the line.
However, as a mature logic family part, lead times and stock levels can vary. No last-time-buy windows or discontinuation notices are in effect.
