It translates logic signals between two independent supply rails, VCCA and VCCB, each operating from 1.08 V to 5.5 V. The part supports data rates up to 200 Mbps, making it suitable for SPI, UART, GPIO, and other moderate-speed interfaces in automotive ECUs, ADAS modules, and body-control units. The 14-WQFN package with wettable flank enables automated solder-joint inspection, a requirement for high-reliability automotive production lines. ## Supply range and what it means for the BOM Both VCCA and VCCB accept the same 1.08 V to 5.5 V range, covering standard logic levels without separate voltage regulators. ## 200 Mbps — speed tier check The 200 Mbps data rate covers most on-board serial buses. It will not handle DDR memory interfaces or high-speed serial links like LVDS. ## Wettable flank — why it matters for production The 14-WQFN package has a wettable flank, meaning the side of the package terminal is plated to accept solder. This allows automated optical inspection (AOI) to verify solder-joint quality after reflow — a standard requirement in automotive electronics manufacturing. Without it, you would need X-ray inspection to confirm hidden solder joints under the QFN. ## Lifecycle and sourcing It is ROHS3 compliant. For dual-sourcing flexibility, the TXU0304BQAR is a functional alternative — same 200 Mbps data rate, unidirectional, 4 channels, and similar supply range — though it lacks the wettable flank and may not carry AEC-Q100 qualification.","metaTitle":"TXU0104QWBQARQ1 Voltage Level Translator, AEC-Q100, 200 Mbps","metaDescription":"TI TXU0104QWBQARQ1 automotive AEC-Q100 unidirectional voltage-level translator, 4 channels, 1.08 V to 5.5 V supply, 200 Mbps data rate, 14-WQFN with wettable","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR)","Data Rate":"200Mbps","Output Type":"Tri-State","Channel Type":"Unidirectional","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"14-WFDFN Exposed Pad","Voltage - VCCA":"1.08 V ~ 5.5 V","Voltage - VCCB":"1.08 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Channels per Circuit":"4","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"14-WQFN (3x2.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.462","stockQuantity":0,"priceTiers":[{"qty":3000,"price":"$0.46200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/de725d693ba558d6c18c3d87173a62e0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TXU0104QWBQARQ1 AEC-Q100 qualified?","answer":"Yes, the TXU0104QWBQARQ1 is part of the Automotive, AEC-Q100 series, qualified for automotive applications."},{"question":"Does TXU0104QWBQARQ1 have a wettable flank for solder inspection?","answer":"Yes, the 14-WQFN package includes a wettable flank, enabling automated optical inspection of solder joints after reflow."},{"question":"What is the difference between TXU0104QWBQARQ1 and TXB0104?","answer":"The TXU0104 is unidirectional, while the TXB0104 is bidirectional.
