TCA9534PWR Frequently Asked Questions (FAQs)

  • The TCA9534PWR can support I2C bus frequencies up to 400 kHz.
  • To configure the TCA9534PWR to operate in input mode, set the corresponding bit in the Input/Output Register (I/O Reg) to '1'. This will configure the pin as an input.
  • The TCA9534PWR can sink or source up to 25 mA per pin.
  • The TCA9534PWR 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 TCA9534PWR 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.
