PIN DESCRIPTION
1 inhibit output for switching an external voltage regulator if a wake-up signal occurs
2 transmit data input for activating the driver to the bus lines
3 receive data output for reading out the data from the bus lines
4 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)
5 standby digital control signal input (active LOW); defines together with input signal on pin EN the
state of the transceiver (in normal and low power modes); see Table 2 and Fig.3
6 enable digital control signal input; defines together with input signal on pin STB the state of the
transceiver (in normal and low power modes); see Table 2 and Fig.3
7 local wake-up signal input; falling and rising edges are both detected
8 termination resistor connection; in case of a CANH bus wire error the line is terminated with a
selectable impedance
9 termination resistor connection; in case of a CANL bus wire the line is terminated with a
selectable impedance
