It buffers clock and data lines, operating from a 3V to 3.6V supply rail. Housed in a 20-SSOP package (0.209\", 5.30 mm), it is surface-mount. ## Supply voltage — the 3.3V rail constraint The 3V to 3.6V supply window ties this buffer to a 3.3V I²C bus. Verify the bus voltage before committing the line. ## Package and mounting — 20-SSOP footprint The 20-SSOP package (0.209\" body width, 5.30 mm) is a standard surface-mount footprint. The supplier device package is also 20-SSOP. ## Lifecycle and compliance — active, no LTB risk The PCA9518DBT carries an Active product status with ROHS3 compliance. There is no last-time-buy notice, no NRND flag, and no announced end-of-life. For a BOM freeze or a multi-year production run, this part does not introduce obsolescence risk. The ROHS3 compliance covers the current EU directive without exemptions.","metaTitle":"PCA9518DBT I²C Buffer, 20-SSOP, 3V–3.6V – Active","metaDescription":"PCA9518DBT is an active I²C buffer IC in a 20-SSOP package, 3V to 3.6V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Applications":"Buffer","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Supplier Device Package":"20-SSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.59","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.59000","currency":"USD"},{"qty":10,"price":"$2.32600","currency":"USD"},{"qty":25,"price":"$2.19440","currency":"USD"},{"qty":100,"price":"$1.86950","currency":"USD"},{"qty":250,"price":"$1.75536","currency":"USD"},{"qty":500,"price":"$1.53594","currency":"USD"},{"qty":1250,"price":"$1.27264","currency":"USD"},{"qty":2500,"price":"$1.24200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7f9ba0a25253cc624fbe7d1572f6b44d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is PCA9518DBT obsolete or active?","answer":"The PCA9518DBT is Active in production.
