This part is designed for industrial control, military/aerospace, and other environments requiring wide temperature tolerance and reliable bus isolation. For a design that needs a through-hole logic part with military temperature range, this is a stable, long-term sourcing choice. The 74HCT family is mature but still in broad production, so supply through independent distribution remains consistent. ## Board-level fit: 14-DIP footprint and 5V supply rail The 14-DIP (0.300\", 7.62mm) package is a standard through-hole footprint — no surprises for rework or manual assembly. It mates to a 14-pin DIP socket or direct solder into plated through-holes. The 6mA output drive is modest — fine for driving a few CMOS inputs or a short backplane trace, but not for heavy capacitive loads or long cables. For higher fan-out, consider a bus transceiver with 24mA or 32mA drive.","metaTitle":"CD74HCT243EE4 74HCT Transceiver, Non-Inverting, 14-DIP","metaDescription":"CD74HCT243EE4 74HCT series transceiver, non-inverting with 3-state outputs. 4.5V-5.5V supply, 6mA drive, through-hole 14-DIP package.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74HCT","Package":"Bulk","Logic Type":"Transceiver, Non-Inverting","Output Type":"3-State","Mounting Type":"Through Hole","Package / Case":"14-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"14-PDIP","Current - Output High, Low":"6mA, 6mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.59","stockQuantity":0,"priceTiers":[{"qty":513,"price":"$0.59000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/85dc1d19a1677f58c9d16b8a470758fc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many bits does CD74HCT243EE4 have?","answer":"It is a 4-bit transceiver: one element with four bits per element."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HCT243EE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HCT243EE4 when reusing this data.
