General 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. The high voltage range and
the low standby current as well as the wide tempera-
ture range make the IC interesting for a wide field of
applications. An implemented over temperature pro-
tection disables the bus driver to prevent damages. Bus
voltage excursions from –
24V
to +
30V
ensures easy
board protection.
