It belongs to the 74HCT family, which means it accepts TTL-level input thresholds while running from a standard 5V CMOS supply rail. Each output can sink or source 6mA, making it suitable for driving moderate bus loads or LED indicators without external transistors. The 3-state control lets you disconnect the outputs from a shared data bus when the chip is not selected, preventing bus contention. ## Supply rail and temperature – where it fits The supply range is tight: 4.5V to 5.5V, so plan for a regulated 5V rail. No 3.3V operation. If your design lives in a commercial 0°C–70°C office environment, this part still works but you are paying for a wider range you do not need. ## Lifecycle – no last-time-buy panic Renesas still manufactures this part, so there is no EOL clock ticking for new designs. For dual-sourcing, look for a 74HCT240 in the same package from another manufacturer.","metaTitle":"74HCT240FPVEL-E Buffer Inverting 3-State, 5V Supply","metaDescription":"74HCT240FPVEL-E is an active 74HCT-series buffer/inverting line driver with 3-state outputs. 4.5V–5.5V supply, 6mA drive, industrial temp range.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74HCT","Package":"Bulk","Logic Type":"Buffer, Inverting","Output Type":"3-State","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"2","Operating Temperature":"-40°C ~ 125°C (TA)","Current - Output High, Low":"6mA, 6mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6","stockQuantity":0,"priceTiers":[{"qty":503,"price":"$0.60000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/t913jotbbf/RNCCS19345-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"Can 74HCT240FPVEL-E handle 5V input logic?","answer":"Yes. The 74HCT family is designed to accept TTL-level input thresholds, which are compatible with 5V logic. The supply range is 4.5V to 5.5V, so it runs on a standard 5V rail."},{"question":"Is 74HCT240FPVEL-E a 3-state output buffer?","answer":"Yes. The outputs are 3-state, meaning they can be actively driven high or low, or placed in a high-impedance state to disconnect from a shared bus."},{"question":"What are the best equivalents or cross-referenced parts for 74HCT240FPVEL-E?","answer":"No official cross-reference is listed in the record. However, the 74HCT240 function is widely second-sourced; look for a 74HCT240 in the same package from TI, Nexperia, or other vendors for a drop-in replacement. The 74FCT16245ATPVG is a different logic family (74FCT) and is a non-inverting transceiver, not a direct equivalent."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/74HCT240FPVEL-E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/74HCT240FPVEL-E when reusing this data.
