TCA9535DBT Frequently Asked Questions (FAQs)

  • The TCA9535DBT can support I2C bus frequencies up to 400 kHz.
  • To configure the TCA9535DBT to operate in input mode, set the corresponding bit in the Input/Output Configuration Register (Register 0x06) to 1. This will configure the pin as an input.
  • Yes, the TCA9535DBT can be used to drive LEDs. However, the maximum current sink capability of the device is 25 mA per pin, so you may need to use external transistors or resistors to drive higher-current LEDs.
  • The TCA9535DBT can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
  • The power-on default state of the TCA9535DBT is that all pins are configured as inputs, and the output values are undefined.
