    Description
    INH
    1
    inhibit output for switching an external voltage regulator if a
    wake-up signal occurs
    TXD
    2
    transmit data input for activating the driver to the bus lines
    RXD
    3
    receive data output for reading out the data from the bus lines
    ERR
    4
    error, wake-up and power-on indication output; active LOW in
    normal operating mode when a bus failure is detected; active LOW
    in standby and sleep mode when a wake-up is detected; active
    LOW in power-on standby when a VBAT power-on event is detected
    STB
    5
    standby digital control signal input; together with the input signal
    on pin EN this input determines the state of the transceiver;
    EN
    6
    enable digital control signal input; together with the input signal on
    pin STB this input determines the state of the transceiver;
    WAKE
    7
    local wake-up signal input (active LOW); both falling and rising
    edges are detected
    RTH
    8
    termination resistor connection; in case of a CANH bus wire error
    the line is terminated with a predened impedance
    RTL
    9
    termination resistor connection; in case of a CANL bus wire error
    the line is terminated with a predened impedance
