there is no need for buffers at all if your cable is not too long,
 <= 1 meter

the problem is that ispLSI22V10 is so expensive comparing to what
it has inside that it makes the use not reasonable in most designs.
16V8 is dirt cheap .7 USD (1.09 DEM)
22V10 is still cheap at 1.5 (2.3 DEM) if I recall the prices correct

but ispLSI is way much more :(
ispLSI1016 offers more for the bucks as ispLSI22V10 and is also
in system programmable
