TCA6424RGJR Frequently Asked Questions (FAQs)

  • The maximum current that can be sourced or sunk by each I/O pin is 25mA.
  • The TCA6424RGJR is configured for I2C bus operation by setting the A0 and A1 pins to VCC or GND to select the I2C address. The device is then controlled using I2C commands.
  • The reset pin (RST) is used to reset the device to its default state. When the RST pin is pulled low, the device resets and all I/O pins are set to inputs.
  • The interrupt feature on the TCA6424RGJR is used to notify the microcontroller of changes on the I/O pins. The interrupt pin (INT) is asserted low when a change is detected on any of the I/O pins. The interrupt can be cleared by reading the interrupt status register.
  • The maximum frequency of operation for the TCA6424RGJR is 400 kHz for I2C bus operation.
