That is typical for through-hole or ceramic flat-pack devices in the 54LS family. Plan for manual or tube-fed insertion; it will not feed through a pick-and-place machine without a carrier.","metaTitle":"54LS51FMQB AND-OR-INVERT Gate, LS Series, Active","metaDescription":"54LS51FMQB is an AND-OR-INVERT gate from the 54LS series, active lifecycle.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.34","priceTiers":[{"qty":224,"price":"$1.34000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4d04f5a61994191e57415344c33df133.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/54LS51FMQB/alternatives.json"},"ai":{"faq":[{"question":"What is the function of 54LS51FMQB?","answer":"It performs the logic function (A·B)+(C·D) inverted — a standard combinatorial logic building block."},{"question":"What are the alternatives to 54LS51FMQB?","answer":"The 4030BDM is a peer part in the same functional class — a quad XOR gate — but it is a different logic function (XOR vs AND-OR-INVERT).
