Note 1:
As defined by ISO, bus value is one of two complementary logical values: dominant or recessive. The dominant value repre-
sents the logical 1 and the recessive represents the logical 0. During the simultaneous transmission of the dominant and
recessive bits, the resulting bus value is dominant. For MAX3050 and MAX3057 values, see the truth table in the
Transmitter
and
Receiver
sections.
