Product details

What this level translator does that a fixed-direction buffer won't

The Texas Instruments TXS0104ERGYRG4 is a 4-channel bidirectional voltage-level translator that handles open-drain and push-pull signals without a direction-control pin. 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.

Frequently asked questions

Can TXS0104ERGYRG4 be used for I2C level shifting?

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.

What is the difference between TXS0104ERGYRG4 and TXB0104?

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.

Is TXS0104ERGYRG4 a direct replacement for TXS0104ERGYR?

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.

Does TXS0104ERGYRG4 support auto-direction sensing?

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.

Is TXS0104ERGYRG4 compatible with 1.8 V and 3.3 V?

Yes. This covers the common 1.8 V-to-3.3 V and 3.3 V-to-5 V translation scenarios.
