The 2-line-input architecture makes it a direct fit for data-routing and bus-selection logic in legacy TTL-based systems. ## Active production, RoHS constraint The RoHS non-compliance means this part uses lead-bearing solder terminations — a factor for BOMs that must meet RoHS directives. ## Sourcing and fit for legacy designs The active status means we can source it against an RFQ — confirm the exact quantity and target lead time with a quote request.","metaTitle":"54S257DM Texas Instruments TTL Multiplexer","metaDescription":"54S257DM Texas Instruments 2-line-input TTL multiplexer, active lifecycle, Bulk package, RoHS non-compliant.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.25","stockQuantity":0,"priceTiers":[{"qty":241,"price":"$1.25000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eb9c13c6da3495d6ea048af42fbf6993.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 54S257DM RoHS compliant?","answer":"No — the 54S257DM is listed as RoHS non-compliant, meaning it contains lead.
