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 the bus
has a failure, and in low power modes (wake-up signal or in power-on standby)
standby digital control signal input (active LOW); together with the input signal on pin EN this input
determines the state of the transceiver (in normal and low power modes); see Table 2 and Fig.3
enable digital control signal input; together with the input signal on pin STB this input determines
the state of the transceiver (in normal and low power modes); see Table 2 and Fig.3
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
