Description
This device provides a bidirectional, half-duplex
communication physical interface to automotive and
industrial LIN systems to meet the LIN bus specification
Revision 2.1 and SAE J2602. The device is short circuit
and overtemperature protected by internal circuitry.
The device has been specifically designed to operate in
the automotive operating environment and will survive
all specified transient conditions while meeting all of the
stringent quiescent current requirements.
