PCA9548ADW Frequently Asked Questions (FAQ)

  • The PCA9548ADW can support I2C bus frequencies up to 400 kHz, but it's recommended to operate at 100 kHz or lower for reliable operation.

  • To configure the PCA9548ADW for multiple masters, connect the SCL and SDA pins of each master to the corresponding pins on the PCA9548ADW. Then, use the EN pins to enable or disable each master's access to the bus.

  • The PCA9548ADW can drive I2C buses with capacitances up to 400 pF. However, it's recommended to keep the bus capacitance below 200 pF for reliable operation.

  • Yes, the PCA9548ADW can switch between multiple I2C buses with different voltage levels, but the voltage on each bus must be within the recommended operating range of 1.65 V to 5.5 V.

  • The PCA9548ADW can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
