TCA9534ADWT Frequently Asked Questions (FAQs)

  • The TCA9534ADWT can support I2C bus frequencies up to 400 kHz.
  • Yes, the TCA9534ADWT can be used as a level shifter. It has a built-in voltage translator that allows it to operate with a supply voltage range of 1.65 V to 5.5 V, making it suitable for level shifting applications.
  • To configure the TCA9534ADWT for use with a microcontroller, you need to connect the SCL and SDA pins to the microcontroller's I2C bus, and then use the microcontroller's I2C library to communicate with the TCA9534ADWT. You will also need to configure the TCA9534ADWT's registers to set the desired output state and configuration.
  • The TCA9534ADWT can sink or source up to 25 mA of current per output pin.
  • Yes, the TCA9534ADWT can be used to drive LEDs. However, the maximum current that the device can sink or source per output pin is 25 mA, so you may need to use external resistors to limit the current to the LEDs.
