Operating temperature range is -55°C to 125°C. ## Package and footprint Package is 20-SOIC with 0.295\" body width, supplied in Tube. ## Lifecycle and compliance ROHS3 compliant, so it ships lead-free and meets EU RoHS requirements without an exemption. No AEC-Q automotive qualification cited, so it stays in industrial/military/commercial domains unless you qualify it yourself.","metaTitle":"Texas Instruments CD74AC540M Buffer Inverting, 3-State","metaDescription":"Texas Instruments CD74AC540M 74AC series buffer/inverting line driver with 3-state outputs. 1.5V–5.5V supply, 24mA drive, -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":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-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":"20-SOIC","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.29","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.29000","currency":"USD"},{"qty":10,"price":"$1.15100","currency":"USD"},{"qty":25,"price":"$1.09240","currency":"USD"},{"qty":100,"price":"$0.89720","currency":"USD"},{"qty":250,"price":"$0.83868","currency":"USD"},{"qty":500,"price":"$0.74116","currency":"USD"},{"qty":1000,"price":"$0.58512","currency":"USD"},{"qty":2500,"price":"$0.55200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b5e14e7aa20bf89f547d366e88041793.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD74AC540M RoHS compliant?","answer":"Yes, the CD74AC540M is ROHS3 compliant — it meets the latest EU RoHS directive without exemptions."},{"question":"What is the replacement or equivalent for CD74AC540M?","answer":"The CD74AC540M is an active part with no official replacement.
