low 0.5V, the termination network is SE. Between 0.7V
and 1.9V, the termination network switches to LVD, and
above 2.4V is HVD, causing the terminators to discon-
nect from the bus. The thresholds accommodate differ-
ences in ground potential that can occur with long lines.
Three UCC5673 multi-mode parts are required at each
end of the bus to terminate 27 (18 data, plus 9 control)
lines. Each part includes a DIFSENS driver, but only one
is necessary to drive the line. The DIFFB inputs on all
three parts are connected together, allowing them to
share the same 50Hz noise filter. This multi-mode termi-
nator
operates

TRMPWR voltage. This accommodates 3.3V systems,
with allowance for the 3.3V supply tolerance (+/- 10%), a
unidirectional fusing device and cable drop. In 3.3V
