I would like this question answered as well. I have a 12V supply and Iset of 50mA. Do I need to put a resistor there? what size?

Please read datasheet in details before using the part.

Because PWM1 controls OUT1/2, PWM2 controls OUT3/4. Use OUTPUT5/6/7/8 for unused pin and pull down the PWM3/4 to GND.

What if you are using 7/8 ports. What do we need to do for the last port?

If for OUT7 or OUT8, there is only one channel is used, recommend to add a resistor or diode as a dummy load to avoid fault report.
