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 temperature range make the IC interesting for a wide field of applications.
