Symbol Pin 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 V
BAT
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;
see Table 5
and Figure 3
EN 6 enable digital control signal input; together with the input signal on
pin STB
this input determines the state of the transceiver;
see Table 5
and Figure 3
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 predefined impedance
RTL 9 termination resistor connection; in case of a CANL bus wire error
the line is terminated with a predefined impedance
