If a machine was designed for a 74194, a 74F194 will at best be an
adequate replacement, but it won't be better.
The 74F194 is faster, but that isn't necessarily an improvement.
As part of being faster, it has faster edge (slew) rates on its
outputs, which can cause problems. It also draws higher transient
currents.
