PCA9545APW,112 Frequently Asked Questions (FAQs)

  • The PCA9545APW,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 PCA9545APW,112 can be used as a level shifter for I2C signals, but it's not recommended as it's primarily designed as a bus multiplexer. For level shifting, a dedicated level shifter IC is recommended.
  • To ensure correct switching, make sure to follow the recommended switching sequence in the datasheet, and use the EN pin to enable or disable the switch. Also, ensure that the I2C bus is idle before switching.
  • The PCA9545APW,112 can drive up to 400 pF of capacitance on the I2C bus, but it's recommended to keep the capacitance as low as possible to ensure reliable operation.
  • No, the PCA9545APW,112 is specifically designed for I2C bus multiplexing and should not be used for other types of buses. Using it for other buses may result in unreliable operation or damage to the device.
