Function
Receive data output;
External Pull Up necessary
LOW in dominant state, active LOW after a Wake-Up event at BUS or WK pin
Enable input;
integrated pull-down, device set to normal operation mode when HIGH
Wake input;
active LOW, negative edge triggered, internal pull-up
Transmit data input;
integrated pull-down, LOW in dominant state; active LOW after Wake-Up via WK pin
Ground
Bus input / output;
LIN bus line input / output
LOW in dominant state
Internal termination and pull-up current source
Battery supply input
Inhibit output;
battery supply related output
HIGH (V_S) in Normal and Stand-By operation mode
can be used to control an external voltage regulator
can be used to control external bus termination resistor when the device will be used
as Master node
