Can I use this for I2C communication?

No. The TXB0108 is designed specifically for push-pull CMOS logic. For open-drain applications like I2C or 1-Wire, use the TI TXS010X series.

What are the key specifications?

It supports 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port, with data rates up to 100 Mbps and ±15-kV ESD protection on the B-port.

What should I consider for PCB layout?

Keep trace lengths short to minimize capacitive loading. The one-shot circuitry is sensitive to reflections; excessive capacitance can cause re-triggering or oscillations.

What is the supply requirement?

VCCA must be less than or equal to VCCB (VCCA ≤ VCCB) at all times during operation.

What should sourcing teams check before buying TXB0108PWR?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.
