The wide supply range from 2V to 6V means it can interface directly with 3.3V and 5V logic families on the same board without external level shifters — a practical advantage when bridging a 3.3V MCU to a 5V peripheral bus. Output drive is 24mA per channel, enough for most backplane or memory-bus loads, though you'll want to check the capacitive load if the trace runs more than a few inches. The 20-SSOP package (0.209-inch body width, 5.30mm) is a standard 1.27mm pitch gull-wing lead form.","metaTitle":"SN74AC245DBR 74AC Transceiver, 24mA, 20-SSOP, Active","metaDescription":"TI SN74AC245DBR 74AC series 8-bit non-inverting transceiver with 3-state outputs, 2V–6V supply, 24mA drive, -40°C to 85°C, 20-SSOP.","metaKeywords":null},"attributes":{"series":"74AC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74AC","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Transceiver, 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":"2V ~ 6V","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SSOP","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.91","priceTiers":[{"qty":1,"price":"$0.91000","currency":"USD"},{"qty":2000,"price":"$0.43500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/92bd84f8d14631869e51e79f44538188.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74AC245DBR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN74AC245 and SN74HCT245?","answer":"The SN74AC245 runs from 2V to 6V and uses advanced CMOS (AC) logic for higher speed and lower power at 3.3V. The SN74HCT245 is a TTL-compatible version that operates at 4.5V to 5.5V and has slower propagation delays. If your design runs at 3.3V, the 74AC245 is the better fit; at 5V with TTL thresholds, the 74HCT245 works."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AC245DBR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AC245DBR when reusing this data.
