Don't do it.  Code requires separation for safety.  For optimal
performance stay 12" minimum from 110VACD and 24" from 220VAC.  Cross
at right angles where necessary.  That said, it's ok to run close and
parallel for a few feet, say up a wall to a light switch.  But
farther than that keep your distance.

For short distances necessary to get to a service point from the main
run, it's ok to stay under 12" away.  Don't run the two types
abutting each other though.
