PCA9548ADB Frequently Asked Questions (FAQs)

  • The PCA9548ADB can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • Yes, the PCA9548ADB can be used as a level shifter for I2C signals, allowing you to interface devices with different voltage levels.
  • To configure the PCA9548ADB in dual-bus mode, you need to connect the EN pin to VCC, and then use the A0 and A1 pins to select one of the four possible bus configurations.
  • The PCA9548ADB can drive up to 400 pF of capacitance on the I2C bus, but it's recommended to limit it to 200 pF for reliable operation.
  • Yes, the PCA9548ADB can be used to connect multiple I2C masters to a single I2C bus, allowing you to create a multi-master I2C system.
