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 over-temperature 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.
