The auto-direction sensing means you don't need a GPIO to steer the data flow — the part decides based on which side drives the bus. Data rate tops out at 24 Mbps, which covers I2C fast-mode plus, SPI, and UART, but not high-speed USB or gigabit Ethernet. At 24 Mbps, this translator handles most board-level serial buses: I2C up to 1 MHz (with appropriate pull-ups), SPI at 10–20 MHz, and UART at any common baud rate. It won't work for 100 Mbps Ethernet RMII or high-speed parallel memory interfaces. The output type supports both open-drain (for I2C) and push-pull (for SPI/UART), so one part covers both signaling styles without external level-shifter ICs. ## Package and footprint notes for the layout engineer The 14-VFQFN exposed pad measures 3.5 mm × 3.5 mm. Mounting is surface-mount only.","metaTitle":"TXS0104ERGYRG4 4-Ch Voltage-Level Translator, 24 Mbps","metaDescription":"Texas Instruments TXS0104ERGYRG4 4-channel bidirectional voltage-level translator. 24 Mbps data rate, auto-direction sensing, 1.65 V to 5.5 V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto-Direction Sensing","Data Rate":"24Mbps","Output Type":"Open Drain, Push-Pull","Channel Type":"Bidirectional","Input Signal":"-","Mounting Type":"Surface Mount","Output Signal":"-","Package / Case":"14-VFQFN Exposed Pad","Voltage - VCCA":"1.65 V ~ 3.6 V","Voltage - VCCB":"2.3 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Base Product Number":"TXS0104","Channels per Circuit":"4","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"14-VQFN (3.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b3a863436fa39d502a61d90ed403fc53.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXS0104ERGYRG4/alternatives.json"},"ai":{"faq":[{"question":"Can TXS0104ERGYRG4 be used for I2C level shifting?","answer":"Yes. The TXS0104E family is designed for open-drain buses like I2C. The auto-direction sensing handles the bidirectional data line (SDA) and clock line (SCL) without an external direction signal. The 24 Mbps data rate is far above I2C's 1 MHz typical ceiling, so there's plenty of margin."},{"question":"What is the difference between TXS0104ERGYRG4 and TXB0104?","answer":"The TXB0104 is a pin-compatible part with the same package and supply ranges, but it is optimized for push-pull signals only. The TXS0104E handles both open-drain and push-pull, making it the correct choice for I2C or any bus that relies on open-drain signaling. If your design uses only push-pull (e.g., SPI, UART), the TXB0104 works, but the TXS0104E is the safer general-purpose pick."},{"question":"Is TXS0104ERGYRG4 a direct replacement for TXS0104ERGYR?","answer":"The TXS0104ERGYRG4 is the Tape & Reel (TR) suffix variant of the base TXS0104ERGYR. The die, package, and electrical specs are identical. The only difference is the shipping medium — TR for reel, CT for cut tape. If your pick-and-place runs from reels, the RG4 suffix is the correct order code."},{"question":"Does TXS0104ERGYRG4 support auto-direction sensing?","answer":"Yes. Auto-direction sensing is the key feature of the TXS0104E family. The translator monitors the bus voltage on each channel and drives the output in the correct direction without a direction-control pin. This simplifies the layout and saves a GPIO on the controller."},{"question":"Is TXS0104ERGYRG4 compatible with 1.8 V and 3.3 V?","answer":"Yes. This covers the common 1.8 V-to-3.3 V and 3.3 V-to-5 V translation scenarios."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TXS0104ERGYRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TXS0104ERGYRG4 when reusing this data.
