Product details

Automotive-grade 8-bit level translator with auto-direction sensing

The auto-direction sensing feature eliminates the need for a direction-control pin; the part determines data flow from the drive strength on each side, which simplifies both PCB layout and firmware overhead.

Rated for 110 Mbps, this translator handles SPI clock rates up to 50 MHz comfortably, plus UART, I2C (in push-pull mode), and general-purpose GPIO expansion. The open-drain output option lets it work on I2C-style multi-drop buses where wired-AND logic is required; push-pull mode gives the full data rate for point-to-point links.

Supply-domain flexibility

That covers the standard logic rails: 1.8 V, 2.5 V, 3.3 V on the A side, and 2.5 V, 3.3 V, 5.0 V on the B side.

Housed in a 20-TSSOP (4.40 mm width) with a 0.65 mm pitch, the footprint is standard for this pin count. The supplier device package is 20-TSSOP, surface-mount only.

Frequently asked questions

Is TXS0108EQPWRQ1 automotive qualified?

Yes, it is listed under the Automotive, AEC-Q100 series, meaning it has passed the stress qualifications required for automotive applications.

Can TXS0108EQPWRQ1 be used for SPI communication?

Yes. With a data rate of 110 Mbps, the part handles SPI clock rates up to 50 MHz easily. The bidirectional channels with auto-direction sensing work well for SPI, though note that the open-drain output mode is not needed for SPI — use push-pull output for full speed.

Is TXS0108EQPWRQ1 compatible with 1.8V and 3.3V systems?

Yes. VCCB accepts 1.65 V to 5.5 V, covering 3.3 V. This part is a natural fit for translating between a 1.8 V MCU and a 3.3 V peripheral.
