Data rate is rated at 100Mbps, fast enough for SPI, UART, and most parallel buses in an automotive ECU. ## What the 100 Mbps data rate means for your bus At 100Mbps, this translator handles typical SPI clock rates up to 50 MHz (double-edge) and UART baud rates well above 1 Mbps. For a 1.8 V sensor communicating with a 3.3 V microcontroller, the 100 Mbps ceiling leaves enough margin for the signal to settle before the next edge. If your bus runs above 100 Mbps — say a QSPI at 80 MHz — the TXB0104 still works, but you need to keep the trace length under 2 inches and place the translator close to the driver to avoid reflections eating into the setup time. ## Package and footprint: 12-UQFN (1.7 mm x 2 mm) The TXB0104QRUTRQ1 comes in a 12-UFQFN package (supplier device package 12-UQFN, 1.7 mm x 2 mm). That is a small footprint — roughly the size of a 0805 resistor — so it fits tight layouts in automotive camera modules or sensor nodes. The pitch is 0.4 mm, which means a standard 0.3 mm stencil aperture for the solder paste; no special assembly tooling required. The exposed pad is not present on this package, so thermal dissipation is through the leads only — keep the ambient below 125°C. No official successor has been announced — this is the part to design in for new automotive programs.","metaTitle":"TXB0104QRUTRQ1 Voltage-Level Translator, AEC-Q100, 100 Mbps","metaDescription":"Texas Instruments TXB0104QRUTRQ1 bidirectional voltage-level translator, AEC-Q100 qualified, 100 Mbps data rate, auto-direction sensing, -40°C to 125°C","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":"12-UFQFN","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":"12-UQFN (1.7x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5200","priceTiers":[{"qty":1,"price":"$1.52000","currency":"USD"},{"qty":10,"price":"$1.36000","currency":"USD"},{"qty":25,"price":"$1.29120","currency":"USD"},{"qty":100,"price":"$1.06050","currency":"USD"},{"qty":250,"price":"$0.99136","currency":"USD"},{"qty":500,"price":"$0.87608","currency":"USD"},{"qty":1000,"price":"$0.69165","currency":"USD"},{"qty":3000,"price":"$0.58800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8c7104bc81a4d76dbf398ba2690793f0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXB0104QRUTRQ1/alternatives.json"},"ai":{"faq":[{"question":"Can TXB0104QRUTRQ1 be used for level shifting between 1.8V and 3.3V?","answer":"Yes.
