PCA9535ECDWR2G Frequently Asked Questions (FAQs)

  • The PCA9535ECDWR2G can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9535ECDWR2G has an internal power-on reset (POR) circuit that resets the device after power-up. However, it is recommended to add an external reset circuit to ensure a clean reset signal, especially in noisy power supply environments.
  • Yes, the PCA9535ECDWR2G can be used as a level translator between 3.3V and 5V logic levels. The device is designed to operate with a wide range of supply voltages (1.65V to 5.5V) and can translate logic levels between these voltage ranges.
  • When multiple PCA9535ECDWR2G devices are connected to the same I2C bus, each device must have a unique address. This can be achieved by connecting the A0, A1, and A2 pins to different logic levels to set the device address. Additionally, it is recommended to use a bus buffer or repeater to improve signal integrity and reduce bus loading.
  • The PCA9535ECDWR2G's GPIO pins can source or sink up to 25mA of current. However, it is recommended to limit the current to 10mA or less to ensure reliable operation and prevent overheating.
