It holds eight bits of data on the latch outputs when the enable is asserted, and passes the D inputs through when enabled — standard addressable-latch behaviour for bus-interface or register-bank applications. One function, one package, eight bits wide. It is RoHS non-compliant, which means it is intended for legacy builds, military/aerospace contracts, or other applications with a RoHS exemption — not for new designs that require lead-free assembly. This part is — loose devices, not tape-and-reel. For a through-hole board build, Bulk is the standard delivery for low-volume or prototype insertion. No reel or tube orientation to manage; just lead form and insertion.","metaTitle":"54LS259DM D Latch, 8-Bit, TTL, Active","metaDescription":"54LS259DM is an 8-bit D latch with TTL logic, active production, RoHS non-compliant.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2","priceTiers":[{"qty":58,"price":"$5.20000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/10fdf4f787e3baa3a0404e05fcfc3630.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/54LS259DM/alternatives.json"},"ai":{"faq":[{"question":"Is 54LS259DM RoHS compliant?","answer":"No, the 54LS259DM is RoHS non-compliant.
