The 75mA output drive holds across the full temperature band, so a design validated at 25°C does not lose fan-out margin at the extremes. If your system only needs 0°C to 70°C, a 74HC or 74HCT variant may cost less, but for a mil-temp BOM line this is the correct choice.","metaTitle":"CD74ACT257M 74ACT 4x2:1 Multiplexer, 16-SOIC, -55°C to 125°C","metaDescription":"CD74ACT257M is a 74ACT 4 x 2:1 multiplexer in 16-SOIC, 4.5V–5.5V supply, 75mA output drive, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":"74ACT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Multiplexer","Series":"74ACT","Circuit":"4 x 2:1","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Independent Circuits":"1","Operating Temperature":"-55°C ~ 125°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-SOIC","Current - Output High, Low":"75mA, 75mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.29","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.29000","currency":"USD"},{"qty":10,"price":"$1.15700","currency":"USD"},{"qty":25,"price":"$1.09800","currency":"USD"},{"qty":100,"price":"$0.90210","currency":"USD"},{"qty":250,"price":"$0.84324","currency":"USD"},{"qty":500,"price":"$0.74518","currency":"USD"},{"qty":1000,"price":"$0.58830","currency":"USD"},{"qty":2500,"price":"$0.55500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/033e279cfd7e39e153ba79a55ad6efd8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is CD74ACT257M's listed type and series?","answer":"The CD74ACT257M is a Multiplexer (Type) in the 74ACT series.
