Not parallel, but potentially more useful....

Signetics _used_ to make a chip NE5045N that took a digital 
proportional input and output 7 PWM signals.  The 7 analog
inputs to digital proportional output (NE5044N) is still sold, but
Signetics won't comment on how long.

Perhpas you can find a match for the NE5045N, it is/was a VERY useful
chip (and cheap at about $3 in single quantity.)  I would be very 
interested if you score, so please post is so.

What kind of parallel input would you be feeding it?  If you already
have lines dedicated for input into whatever you find, why not just 
generate PWM on them?  It's a matter of timing.  A BASIC STAMP from
PARALLAX could take a serial input and output 7 PWM signals, at $39/ea.
it might or might not be cost effective, but you could but more logic
in it and distribute a bunch of them....

Good luck,
