Single-element architecture means all eight bits are controlled by one output-enable pin. This is a mature 74HCT part — the series has been around for decades — but active means you can still book factory orders through standard distribution without a last-time-buy deadline. For BOM planning, there is no urgency to qualify a second source today, but given the age of the HCT family, it is worth watching for PCN notifications on wafer fab changes or package material shifts that could affect long-term supply. ROHS3 compliant, so no exemption expiry to track for EU markets.","metaTitle":"CD74HCT541M 74HCT Buffer, 20-SOIC, 4.5V-5.5V, -55°C to 125°C","metaDescription":"CD74HCT541M 74HCT non-inverting buffer with 3-state outputs. 4.5V-5.5V supply, 6mA drive, -55°C to 125°C range.

The HC version uses CMOS thresholds (0.3 x VCC and 0.7 x VCC). If your driving device is a 5V TTL output (like a 74LS or 74ALS gate), the HCT variant gives cleaner noise margin. If the driver is another CMOS device running at 5V, either works, but HC typically draws lower quiescent current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HCT541M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HCT541M when reusing this data.
