When the Data (A) input is in the Logic One state and the Data (B)
input is in the Logic Zero state, A
OUT
is equal to V
REF
and B
OUT
is
equal to -V
REF
. This constitutes the Output High state. Data (A) and
Data (B) both in the Logic Zero state causes both A
OUT
and B
OUT
to
be equal to 0V which designates the output Null state. Data (A) in
the Logic Zero state and Data (B) in the Logic One state causes
A
OUT
to be equal to -V
REF
and B
OUT
to be equal to V
REF
which is
the Output Low state.
