TCA6416PWT Frequently Asked Questions (FAQs)

  • The TCA6416PWT can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The TCA6416PWT has an internal POR circuit that resets the device when the supply voltage (VCC) rises above 1.3 V. To ensure proper operation, it is recommended to add a 10 kΩ pull-up resistor to the SCL line and a 10 kΩ pull-down resistor to the SDA line.
  • The TCA6416PWT can drive capacitive loads up to 400 pF on the I2C bus lines (SCL and SDA). Exceeding this limit may cause signal integrity issues.
  • The TCA6416PWT is designed to operate from 1.65 V to 5.5 V. For 5 V operation, ensure that the VCC pin is connected to a 5 V power supply, and the input voltage on the I/O pins does not exceed 5.5 V.
  • The internal pull-up resistors on the I/O pins are designed to provide a default high state on the outputs when the device is powered up or reset. They can be disabled by writing to the corresponding register bits.
