The 3-state outputs let multiple devices share a common data line without contention — the buffer goes high-impedance when the output-enable is deasserted, which is the standard approach for bidirectional bus isolation. ## 20-SSOP footprint and surface-mount assembly The narrow SSOP footprint matches many 20-pin SOIC patterns with a smaller pitch, so verify the land pattern against your existing board before committing the BOM line. Surface-mount assembly is standard for reflow profiles; no special handling beyond MSL precautions. ## Industrial temperature grade and environment The 5V supply rail is common in these settings, and the 74FCT family's bipolar-CMOS process gives it the drive strength to handle capacitive bus loads without excessive propagation delay. ## Output drive and 3-state control Each output can source 15 mA and sink 12 mA, which is typical for 5V bus buffers driving a few TTL loads or a short backplane trace. The 3-state outputs are controlled by the element's output-enable pins (not individually per bit), so the two 4-bit banks can be independently disabled. This matters when you need to isolate one bus segment during power sequencing or boundary scan. ## Lifecycle and sourcing posture It is ROHS3 compliant.","metaTitle":"CY74FCT2240CTQCT Buffer Inverting 3-State 20-SSOP, 5V Supply","metaDescription":"CY74FCT2240CTQCT from the 74FCT series is a dual 4-bit inverting buffer with 3-state outputs.","metaKeywords":null},"attributes":{"series":"74FCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74FCT","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SSOP","Current - Output High, Low":"15mA, 12mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.47000","currency":"USD"},{"qty":10,"price":"$1.31600","currency":"USD"},{"qty":25,"price":"$1.24960","currency":"USD"},{"qty":100,"price":"$1.02640","currency":"USD"},{"qty":250,"price":"$0.95944","currency":"USD"},{"qty":500,"price":"$0.84790","currency":"USD"},{"qty":1000,"price":"$0.66939","currency":"USD"},{"qty":2500,"price":"$0.63150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7c7f1cf9b6c04dc5fbff06356c1f25b6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY74FCT2240CTQCT compatible with 5V logic?","answer":"Yes, it operates on a 4.75V to 5.25V supply, so it is fully compatible with 5V TTL and CMOS logic levels.
