The 6 mA source and 6 mA sink capability per output is typical for HCT buffers — enough to drive a few CMOS or TTL loads directly, but not a high-current backplane. If your bus needs more fan-out, plan on a separate line driver stage. The 3-state outputs allow multiple buffers to share a common bus line when the output-enable control is wired correctly, which is the usual use case for address or data bus isolation. ## Package and mounting reality for the PCB layout engineer The 20-SOIC wide-body (0.295\", 7.50 mm width) footprint is common across many 74HCT and 74HC octal buffers — the same land pattern works for the 74HCT540 (inverting version) and the 74HC541 if you ever cross-ship. The supplier device package is 20-SO, so the standard SOIC-20 wide footprint applies. Surface-mount only; no through-hole variant in this order code. ## Lifecycle and sourcing posture It is a current-production item in the Nexperia 74HCT portfolio.","metaTitle":"74HCT541D118 Buffer, Non-Inverting, 3-State, 20-SOIC","metaDescription":"74HCT541D118 8-bit buffer with 3-state outputs, 4.5V~5.5V supply, -40°C to 125°C, 20-SOIC.","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, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"20-SO","Current - Output High, Low":"6mA, 6mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.22","stockQuantity":0,"priceTiers":[{"qty":1524,"price":"$0.22000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e529d82af22d6db0b48b25bfc419211d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between 74HCT541D118 and 74HC541D118?","answer":"The 74HCT541D118 uses HCT logic levels (TTL-compatible input thresholds at 5 V supply), while the 74HC541D118 uses HC logic levels (CMOS thresholds). If your upstream driver is a 5 V TTL output, the HCT variant guarantees correct input recognition; the HC variant may not. Both are 8-bit non-inverting buffers with 3-state outputs in the same 20-SOIC package."},{"question":"What is the equivalent for 74HCT541D118?","answer":"The closest pin-compatible alternative is the 74HCT540D118, which is the inverting version of the same octal buffer. For a non-inverting equivalent, the 74HC541D118 (same footprint, HC logic levels) or the 74HCT541PW (TSSOP-20 package) are functional alternatives, though the logic family or package differs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/74HCT541D118","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/74HCT541D118 when reusing this data.
