PCA9538DGVR Frequently Asked Questions (FAQs)

  • The PCA9538DGVR can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9538DGVR is configured to operate in 16-bit mode by default. To operate in 8-bit mode, the A0 and A1 pins must be tied to VCC or GND to select the desired mode.
  • Each GPIO pin can source or sink up to 25 mA of current, but the total current sourced or sunk by all GPIO pins should not exceed 100 mA.
  • The PCA9538DGVR can be reset to its default state by applying a low pulse to the RESET pin or by performing a power-on reset (POR).
  • Yes, the PCA9538DGVR can be used as a level translator between 3.3V and 5V systems, but it is recommended to use external resistors to limit the current and voltage on the GPIO pins.
