It belongs to the Automotive, AEC-Q100 series, meaning it has been qualified for automotive-grade reliability and is suitable for use in vehicle electronics, industrial controls, and other harsh environments where temperature and vibration tolerance are required. The translator operates at a data rate of 100 Mbps, sufficient for SPI, UART, GPIO, and most general-purpose digital interfaces. The output type is tri-state, non-inverted, and the device is housed in a 14-TSSOP package (4.40 mm width) for surface-mount assembly. ## Auto-direction sensing — no DIR pin needed The TXB0104QPWRQ1 uses auto-direction sensing to determine the data flow on each channel independently. This means the designer does not need to allocate a GPIO or a control signal to set the direction, which saves board space and reduces firmware complexity. The bidirectional channels are suitable for open-drain buses like I2C, as well as push-pull interfaces such as SPI, UART, and general-purpose GPIO. However, because the auto-sense circuit relies on edge detection, the part is not recommended for applications requiring continuous DC-level translation or for buses with very slow edges (e.g., some I2C implementations at low speeds may need an external pull-up and careful layout). ## Active lifecycle and AEC-Q100 qualification The part is AEC-Q100 qualified, which is the automotive stress-test qualification standard for integrated circuits. This qualification covers a range of reliability tests including high-temperature operating life, temperature cycling, moisture sensitivity, and electrostatic discharge. For buyers sourcing for automotive or high-reliability industrial programs, the AEC-Q100 designation provides documented assurance that the part meets the required quality and reliability benchmarks. The part is also ROHS3 compliant. The device is supplied in a 14-TSSOP package with a body width of 4.40 mm and a 0.65 mm pin pitch. For PCB layout, the 14-TSSOP footprint is a standard JEDEC package, and the land pattern is widely available in most CAD libraries. The part is MSL 3 (Moisture Sensitivity Level 3) per typical TI TSSOP packages — if the moisture-barrier bag has been open for more than 168 hours, a bake before reflow is required to prevent popcorning.","metaTitle":"TXB0104QPWRQ1 Voltage Level Translator, AEC-Q100, 100 Mbps","metaDescription":"Texas Instruments TXB0104QPWRQ1 is a 4-channel bidirectional voltage-level translator with auto-direction sensing.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto-Direction Sensing","Data Rate":"100Mbps","Output Type":"Tri-State, Non-Inverted","Channel Type":"Bidirectional","Input Signal":"-","Mounting Type":"Surface Mount","Output Signal":"-","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Voltage - VCCA":"1.2 V ~ 3.6 V","Voltage - VCCB":"1.65 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Base Product Number":"TXB0104","Channels per Circuit":"4","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"14-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4000","priceTiers":[{"qty":1,"price":"$1.40000","currency":"USD"},{"qty":10,"price":"$1.25400","currency":"USD"},{"qty":25,"price":"$1.19000","currency":"USD"},{"qty":100,"price":"$0.97760","currency":"USD"},{"qty":250,"price":"$0.91388","currency":"USD"},{"qty":500,"price":"$0.80762","currency":"USD"},{"qty":1000,"price":"$0.63759","currency":"USD"},{"qty":2000,"price":"$0.54150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8c7104bc81a4d76dbf398ba2690793f0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXB0104QPWRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TXB0104QPWRQ1 AEC-Q100 qualified?","answer":"Yes, the TXB0104QPWRQ1 is part of the Automotive, AEC-Q100 series, confirming it is qualified to the AEC-Q100 stress-test standard for automotive-grade integrated circuits."},{"question":"Does TXB0104QPWRQ1 support bidirectional level shifting without a direction control pin?","answer":"Yes, the TXB0104QPWRQ1 features auto-direction sensing on all four bidirectional channels, so no direction control pin is needed.
