... Note 1: As defined by ISOSHDN, bus value is one of two complementary logical values: dominant or recessive. The dominant value represents 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 MAX3053 values, see the truth table in the Transmitter and Receiver sections. ...

... When the MAX3053 is in shutdown mode, only the wakeup comparator is active, and normal bus commu- nication is ignored. The remote master of the CAN sys- tem wakes up the MAX3053 with a signal greater than 9V on CANH. The local CAN controller wakes up the MAX3053 by driving SHDN high or TXD. ...
