Yes it is normal that the outputs do not go to 0V. Transistor outputs do not go all the way to 0V. The outputs have a Darlington Transistor driver to give higher gain so the minimum output voltage is 0.7V.   This is designed to drive relays and Infrared Transmitters
If you need the voltage to go to 0V then I suggest you connect a 12V relay like RLY01H to the output. The Relay N/O and Common contacts can be connected to the IN input of the device
