It handles bidirectional data flow on a 5 V bus, controlled by direction and output-enable pins. The single-element, 8-bit-per-element architecture is a straightforward fit for buffering a data or address bus in industrial controllers, telecom line cards, or any 5 V backplane that needs a clean drive stage. Output drive is rated 15 mA source, 12 mA sink, enough for moderate fan-out on a backplane or to drive a handful of CMOS inputs. ## Wide-body 24-SOIC — what the footprint tells you The package is a 24-SOIC with a 7.50 mm body width (0.295\"), the wide-body variant. Surface-mount only; no through-hole option.","metaTitle":"CY74FCT2543ATSOC 74FCT Transceiver, 8-bit, 3-State, 24-SOIC","metaDescription":"CY74FCT2543ATSOC is an 8-bit non-inverting transceiver with 3-state outputs from the 74FCT series. 4.75 V to 5.25 V supply, -40°C to 85°C, 24-SOIC package.","metaKeywords":null},"attributes":{"series":"74FCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74FCT","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":"4.75V ~ 5.25V","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"24-SOIC","Current - Output High, Low":"15mA, 12mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.95000","currency":"USD"},{"qty":10,"price":"$0.85400","currency":"USD"},{"qty":25,"price":"$0.81040","currency":"USD"},{"qty":100,"price":"$0.66560","currency":"USD"},{"qty":250,"price":"$0.62216","currency":"USD"},{"qty":500,"price":"$0.54982","currency":"USD"},{"qty":1000,"price":"$0.43407","currency":"USD"},{"qty":2500,"price":"$0.40950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/537bd0afd0ccba7bce55e42349687c9a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the function of CY74FCT2543ATSOC?","answer":"It is an 8-bit non-inverting transceiver with 3-state outputs, used to buffer bidirectional data on a 5 V bus.
