Description
inhibit output for switching an external voltage regulator if a
wake-up signal occurs
transmit data input for activating the driver to the bus lines
receive data output for reading out the data from the bus lines
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
standby digital control signal input; together with the input signal
on pin EN this input determines the state of the transceiver;
see
enable digital control signal input; together with the input signal on
pin STB this input determines the state of the transceiver;

local wake-up signal input (active LOW); both falling and rising
edges are detected
termination resistor connection; in case of a CANH bus wire error
the line is terminated with a predefined impedance
