Each of the two elements handles four bits, so the part can buffer eight signals total. The 3-state output control lets you tie multiple buffers onto the same data bus without contention — useful in memory-mapped I/O or multiplexed address/data schemes. The 6 mA source and sink capability (per output) is typical for HCT logic; it drives CMOS inputs cleanly and can handle a few low-power loads, but if you need to drive a long backplane trace or a high-capacitance line, plan on a bus transceiver with higher drive. That makes it a candidate for avionics, satellite, downhole drilling, or engine-bay electronics where the board sees extreme cold and heat. Layout needs careful decoupling — a 0.1 µF ceramic right at the supply pin, ground plane underneath, and short traces to the bus lines to keep signal integrity clean at the rated speeds.","metaTitle":"CD74HCT240PWT Buffer, Inverting, 3-State, 20-TSSOP, 74HCT","metaDescription":"CD74HCT240PWT is an active 74HCT inverting buffer with 3-state outputs, 4.5V-5.5V supply, -55°C to 125°C range, 20-TSSOP.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74HCT","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"2","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"20-TSSOP","Current - Output High, Low":"6mA, 6mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.08000","currency":"USD"},{"qty":10,"price":"$0.96600","currency":"USD"},{"qty":25,"price":"$0.91720","currency":"USD"},{"qty":100,"price":"$0.75330","currency":"USD"},{"qty":250,"price":"$0.70420","currency":"USD"},{"qty":500,"price":"$0.62232","currency":"USD"},{"qty":1250,"price":"$0.49131","currency":"USD"},{"qty":2500,"price":"$0.46350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/639bbd2b4b6602f464bccefa5431547a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD74HCT240PWT RoHS compliant?","answer":"Yes, it is ROHS3 compliant, meeting the EU RoHS directive for lead-free and restricted substances."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HCT240PWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HCT240PWT when reusing this data.
