PCA9545ABS,118 Frequently Asked Questions (FAQs)

  • The PCA9545 can handle I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • Yes, the PCA9545 can switch between multiple I2C buses with different voltage levels, but ensure that the voltage levels are within the recommended operating range of 1.65 V to 5.5 V.
  • To ensure correct switching, ensure that the SEL pin is properly driven with a valid logic level (either high or low) and that the bus is not busy during switching. Also, ensure that the I2C bus is idle before switching.
  • The PCA9545 can drive I2C buses with capacitance up to 400 pF, but it's recommended to limit it to 200 pF for reliable operation.
  • Yes, the PCA9545 can switch between I2C buses with different clock frequencies, but ensure that the clock frequencies are within the recommended operating range of 10 kHz to 400 kHz.
