TCA6416AZQSR Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that the TCA6416AZQSR can support?
  The TCA6416AZQSR can support I2C bus frequencies up to 400 kHz.
• How do I configure the TCA6416AZQSR for 5V operation?
  To configure the TCA6416AZQSR for 5V operation, connect the VCC pin to a 5V power supply and ensure that the input voltage on the VIN pin is within the recommended operating range of 4.5V to 5.5V.
• What is the maximum current that the TCA6416AZQSR can sink or source on each I/O pin?
  The TCA6416AZQSR can sink or source up to 25mA of current on each I/O pin.
• How do I reset the TCA6416AZQSR?
  The TCA6416AZQSR can be reset by pulling the RESET pin low for a minimum of 1ms. The device will return to its default state after the reset pin is released.
• What is the purpose of the INT pin on the TCA6416AZQSR?
  The INT pin is an active-low interrupt output that is asserted when an input pin changes state. It can be used to notify the microcontroller of an input change.
