Any supply droop below 3V or overshoot above 3.6V pulls the driver out of its specified operating region. ## 1/0 driver configuration — no receiver on board With one driver and zero receivers, this IC is a unidirectional line driver — it sends a signal but does not listen. That makes it a fit for simplex links like sensor-to-controller or clock distribution, not for bidirectional buses. The 1 Mbps data rate ceiling means the output edge rates are moderate; the buyer should verify that the downstream receiver's input threshold and propagation delay still close the timing budget at the target cable length. ## Active production — no obsolescence concern It is ROHS3 compliant, so it meets the latest EU restriction directive without an exemption expiry to track. ## 16-WQFN package — board-level notes The part is supplied in a 16-WFQFN with exposed pad, supplier device package 16-WQFN (4x4 mm). The reflow profile should follow the JEDEC standard for QFN packages; the exposed pad needs a solder-paste aperture large enough to avoid voids but not so large that it bridges to adjacent pins.","metaTitle":"LMH6555SQ/NOPB Driver IC – 1 Mbps, 3V–3.6V, Industrial Temp","metaDescription":"Texas Instruments LMH6555SQ/NOPB single-channel line driver, 1 Mbps data rate, 3V–3.6V supply, -40°C to 85°C, 16-WQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Driver","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Mounting Type":"Surface Mount","Package / Case":"16-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-WQFN (4x4)","Number of Drivers/Receivers":"1/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.84","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.84000","currency":"USD"},{"qty":10,"price":"$9.02000","currency":"USD"},{"qty":25,"price":"$8.20000","currency":"USD"},{"qty":100,"price":"$7.38000","currency":"USD"},{"qty":250,"price":"$6.76500","currency":"USD"},{"qty":500,"price":"$6.15000","currency":"USD"},{"qty":1000,"price":"$6.15000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/42cf379571d6c91a10c6817a0f334b7f.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMH6555SQ-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMH6555SQ-NOPB when reusing this data.
