TCA9554DWR Frequently Asked Questions (FAQs)

  • The TCA9554DWR can handle I2C clock frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • The TCA9554DWR has an internal POR circuit that resets the device during power-up. To handle POR, ensure that the VCC pin is powered up before the I2C bus is active, and wait for at least 1 ms after power-up before sending I2C commands.
  • Yes, the TCA9554DWR can be used as a level translator between 3.3V and 5V logic. The device is designed to operate with a VCC range of 1.65V to 5.5V, and the input thresholds are compatible with both 3.3V and 5V logic levels.
  • The TCA9554DWR has a configurable output mode. To configure the output mode, write to the Configuration Register (register 0x03) and set bit 0 to 0 for open-drain mode or 1 for push-pull mode.
  • The maximum sink current of the TCA9554DWR outputs is 25 mA per pin, with a total device sink current limit of 100 mA.
