A8423  
LIN Bus Transceiver with Integrated Voltage Regulator  
The A8423 provides the physical interface requirements of the LIN  
(Local Interconnect Network) serial communications bus plus an inte-  
grated voltage regulator that is permanently enabled. These allow the  
development of simple, inexpensive slave nodes in a LIN-Bus system.  
A8423  
The LIN transceiver is compatible with LIN-Bus systems that conform  
to the LIN Protocol Specication, Revision 1.2. It provides all the  
necessary interface and timing control to convert signals to and from  
the bidirectional LIN Bus to individual transmit and receive signals at  
logic-compatible levels.

Control  
The A8423 provides regulated 5V output with a current limit in excess  
of 50 mA. This is sufcient to power a microcontroller handling the  
LIN slave node protocol.
