What do I do with an unused current output to minimize current draw. The unused output will never be turned on with software. I can do any of the following without any trouble.
1) tie the output to ground
2) let the output float (with CMOS parts I want to be VERY sure this is OK)
3) Pull the output up to Vcc with a 10K (or so) resistor.
Unfortunately, the datasheet was a little sparse on this point.
