TCA9535DBR Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that the TCA9535DBR can support?
  The TCA9535DBR can support I2C bus frequencies up to 400 kHz.
• How do I configure the TCA9535DBR to work in inverted mode?
  To configure the TCA9535DBR to work in inverted mode, set the INVERT bit in the Configuration Register (address 0x03) to 1. This will invert the output polarity of the GPIO pins.
• What is the maximum current that the TCA9535DBR can sink or source per GPIO pin?
  The TCA9535DBR can sink or source up to 25 mA of current per GPIO pin.
• How do I reset the TCA9535DBR to its default state?
  To reset the TCA9535DBR to its default state, pull the RESET pin low for at least 1 ms. This will reset all registers to their default values.
• Can I use the TCA9535DBR as a level translator?
  Yes, the TCA9535DBR can be used as a level translator. It can translate voltage levels between 1.8 V and 5 V, making it suitable for use in mixed-voltage systems.
