TCA4311DGKR Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the TCA4311DGKR is 2.7V to 5.5V, although it can tolerate up to 6V for short periods.
  • To ensure proper power-up and initialization, apply a stable voltage supply, and then assert the EN (enable) pin high. Wait for the internal power-on reset (POR) to complete, which takes approximately 10ms.
  • The maximum current rating for the TCA4311DGKR's output drivers is 20mA per pin, with a total current limit of 100mA for all outputs combined.
  • To configure the TCA4311DGKR for I2C or SMBus operation, connect the SCL (clock) pin to the clock signal, and the SDA (data) pin to the data signal. For I2C, use pull-up resistors on both SCL and SDA. For SMBus, use a pull-up resistor only on the SCL pin.
  • The internal pull-up resistors on the TCA4311DGKR are used to pull up the SCL and SDA pins to the supply voltage (VCC) when the device is in a bus-free state, ensuring proper bus idle conditions.
