An implemented over temperature protection disables the bus
driver to prevent damages. Bus voltage excursions from -24V to
+
30V
ensures easy board protection.
The high voltage range and the low standby current as well as the
wide temperature range make the IC interesting for a wide field
of applications.
DESCRIPTION
The IC is designed to control bidirectional serial data transmission
on bus lines. It supports both LIN- and K-Bus which are selected
by the MODE pin. This feature allows an easy migration from K- to
LIN-bus without changing the transceiver.
