I too have had timing problems with the Philips 74HC123 parts.  The
Philips part produced a significantly shorter pulse than Fairchild's
part.  We use the part for a long pulse (30 seconds or so) and by
using much larger capacitors could still only get to about 26 seconds.

I don't know if this will affect your application, but I can verify the
Philips' part is different.
