PCA9555RGER Frequently Asked Questions (FAQ)

  • The PCA9555RGER can support I2C bus frequencies up to 400 kHz.

  • To use an external pull-up resistor, connect the resistor between the SCL/SDA pins and the VCC pin. The recommended value is 1 kΩ to 10 kΩ.

  • The PCA9555RGER can sink or source up to 25 mA of current on each GPIO pin.

  • Yes, the PCA9555RGER can be used as a level translator between 3.3V and 5V systems. However, ensure that the VCC pin is connected to the higher voltage system (5V) and the GPIO pins are connected to the lower voltage system (3.3V).

  • The PCA9555RGER can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
