That means one fewer GPIO on the microcontroller and no firmware toggling a DIR line during bus turnarounds — useful when you are translating a mix of I²C, SPI chip selects, and GPIO between a 1.8 V or 3.3 V host and a 5 V peripheral. The part handles both open-drain and push-pull outputs, so it covers multi-master buses and single-ended signalling in the same package. ## 60 Mbps — fast enough for most serial, not for parallel memory The 60 Mbps data rate translates to roughly 60 MHz clock-equivalent on a single edge, which comfortably handles SPI at 50 MHz, UART at several Mbps, and general-purpose GPIO toggling. It will not work for DDR memory interfaces or high-speed parallel busses, but for the common case of bridging an MCU to a sensor, display, or legacy ASIC, the margin is generous. The auto-direction architecture introduces a propagation delay around 4–6 ns typical; budget that into your setup-and-hold timing if you are running near the rate limit. The 5.5 V ceiling on VCCB is the hard limit — a 5 V rail that regulation holds at 5.0 V ±5% is fine; an unregulated 5 V supply that can hit 5.6 V at light load is not. The part is bidirectional, so data flows both ways simultaneously on different channels without a direction pin. Housed in a 20-TSSOP (4.40 mm body width), surface-mount. The supplier device package is 20-TSSOP.","metaTitle":"TXS0108EPWR 8-bit bidirectional voltage-level translator","metaDescription":"TI TXS0108EPWR 8-channel bidirectional level shifter, 1.4V–3.6V VCCA / 1.65V–5.5V VCCB, 60 Mbps data rate, auto-direction sensing, 20-TSSOP.","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":"60Mbps","Output Type":"Open Drain, Push-Pull","Channel Type":"Bidirectional","Input Signal":"-","Mounting Type":"Surface Mount","Output Signal":"-","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Voltage - VCCA":"1.4 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":"TXS0108","Channels per Circuit":"8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.53495","priceTiers":[{"qty":1,"price":"$0.53495","currency":"USD"},{"qty":10,"price":"$0.43329","currency":"USD"},{"qty":30,"price":"$0.38351","currency":"USD"},{"qty":100,"price":"$0.33937","currency":"USD"},{"qty":500,"price":"$0.32599","currency":"USD"},{"qty":1000,"price":"$0.32024","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/53f4a1d7859715e0db44817f72c154d4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TXS0108EPWR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TXS0108EPWR and TXB0108PWR?","answer":"Both are 8-bit bidirectional voltage-level translators from TI in the same 20-TSSOP package. The TXB0108PWR uses a different output-driver architecture that provides higher drive strength at the cost of slightly higher quiescent current. The TXS0108EPWR is optimized for lower power and auto-direction sensing with open-drain compatibility, making it a better fit for I²C and other multi-master busses. Pin-compatible between the two, so a board can be stuffed with either if the drive requirements are met."},{"question":"Can TXS0108EPWR be used for 3.3V to 5V level shifting?","answer":"Yes.
