Design Notes
Ensure both VCCA and VCCB are powered and within the specified range (0.9V to 3.6V). The voltage difference between VCCA and VCCB should not exceed the absolute maximum ratings. Place 0.1uF decoupling capacitors close to each power pin to minimize noise and ensure stable operation.
Keep traces between the TXB0304RSVR and connected devices as short as possible to minimize parasitic capacitance and signal degradation. Use a solid ground plane and avoid routing high-speed signals near noisy power lines. The UQFN package has an exposed pad; solder it to the PCB for better thermal performance.
Do not leave unused I/O pins floating; tie them to a defined logic level through pull-up or pull-down resistors. When using the isolation feature, ensure that if one VCC is at GND, the other VCC is also powered down to prevent backflow current. Verify the direction sensing works correctly with your specific bus topology.
Compliance Information
RoHS compliant and lead-free per DigiKey and TI datasheet. AEC-Q100 not applicable for this non-automotive part.
