It sits between the slower 74LS and the faster 74ABT/74LVTH families, offering a balanced speed-power point for bus-oriented data flow. The 24 mA symmetric output drive at both high and low levels is enough to drive a heavily loaded backplane or a memory-address bus with a dozen loads.","metaTitle":"CD74AC646M 74AC Transceiver, 24-SOIC, 1.5V–5.5V","metaDescription":"CD74AC646M 74AC 8-bit non-inverting transceiver with 3-state outputs, 24-SOIC, 1.5V–5.5V supply, military temp range -55°C to 125°C.","metaKeywords":null},"attributes":{"series":"74AC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74AC","Package":"Tube","Logic Type":"Transceiver, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"24-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"24-SOIC","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.06","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.06000","currency":"USD"},{"qty":10,"price":"$2.74700","currency":"USD"},{"qty":25,"price":"$2.59160","currency":"USD"},{"qty":100,"price":"$2.20810","currency":"USD"},{"qty":250,"price":"$2.07336","currency":"USD"},{"qty":500,"price":"$1.81420","currency":"USD"},{"qty":1000,"price":"$1.50319","currency":"USD"},{"qty":2500,"price":"$1.46700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/db008d42fb347e6b977a1cec548a80bf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD74AC646M RoHS compliant?","answer":"Yes, the CD74AC646M is listed as ROHS3 Compliant."},{"question":"What is the closest functional equivalent to CD74AC646M?","answer":"For a drop-in replacement that keeps the wide supply range and military temperature rating, the CD74AC646M itself is the part to source."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74AC646M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74AC646M when reusing this data.
