PCA9540BD,112 Frequently Asked Questions (FAQ)

  • The PCA9540BD,112 can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.

  • Yes, the PCA9540BD,112 can switch between multiple I2C buses with different voltage levels, but ensure that the voltage levels are within the recommended operating range of 1.8 V to 5.5 V.

  • To ensure correct switching, ensure that the enable pins (EN0-EN3) are properly controlled, and the bus selection pins (A0-A2) are correctly configured according to the datasheet.

  • The PCA9540BD,112 can sink or source up to 3 mA of current on the I2C bus, but it's recommended to limit the current to 1 mA for reliable operation.

  • Yes, the PCA9540BD,112 is suitable for hot-swappable I2C bus applications, but ensure that the power-up and power-down sequences are properly controlled to avoid bus conflicts.
