TCA9554PWR Frequently Asked Questions (FAQ)

  • The TCA9554PWR can support I2C bus frequencies up to 400 kHz.

  • To configure the TCA9554PWR to operate in input mode, set the corresponding bit in the configuration register (register 0x03) to 1. This will enable the input mode for the respective pin.

  • The TCA9554PWR can sink or source up to 25 mA per pin.

  • The TCA9554PWR can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.

  • The internal pull-up resistors on the TCA9554PWR are used to pull up the I2C bus lines (SCL and SDA) to the supply voltage (VCC) when the device is not actively driving the bus.
