The 0.209-inch width fits the common SSOP-20 land pattern; verify your PCB footprint against the mechanical drawing if you're replacing a different 20-pin package. Surface-mount only — no through-hole variant in this order code. ## Temperature grade and where it runs Rated for -40°C to 85°C ambient, which covers industrial control cabinets, outdoor telecom pedestals, and factory-floor I/O racks. Not qualified to AEC-Q100, so skip it for under-hood automotive or other extended-temperature environments without your own qualification data. ## Lifecycle and sourcing note TI lists the SN74ACT244DB as Active with ROHS3 compliance. No end-of-life notice on record, so it's still a valid BOM line for new builds.","metaTitle":"SN74ACT244DB 74ACT Buffer, Non-Inverting, 3-State, 20-SSOP","metaDescription":"Active SN74ACT244DB from TI 74ACT series: 4.5V–5.5V supply, 24mA drive, industrial temp -40°C to 85°C, 20-SSOP.","metaKeywords":null},"attributes":{"series":"74ACT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74ACT","Package":"Bulk","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SSOP","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.42","stockQuantity":0,"priceTiers":[{"qty":722,"price":"$0.42000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/104b54a04175ede002fe1ebc57359cbc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SN74ACT244DB and SN74ACT244DWR?","answer":"Both are the same 74ACT244 buffer in a 20-pin SSOP.
