How do I connect a system with bidirectional 5V signals to a system with 3V signals using the MAX11300?

Pairs of adjacent PIXI ports can also form bidirectional level translator paths that are targeted to operate with open-drain drivers. When used as a bidirectional level translator, the pair of PIXI ports must be accompanied with external pullup resistors to meet the proper logic level. For example, use a 10kΩ pullup from each port to the 5V or 3V rails.
