features
description
on bus lines. It supports both LIN- and K-Bus which are selected
ÿ K-Bus Interface applicable as diagnostic
The IC is designed to control bidirectional serial data transmission
interface to ISO 9141 and OBD II
ÿ Change between LIN-mode and K-mode
pinning
by the MODE pin. This feature allows an easy migration from K- to
with external pin
LIN-bus without changing the transceiver.

ÿ Data rate up to 9.600Baud for K-mode
ÿ Data rate up to 20kBaud for LIN-mode
The high voltage range and the low standby current as well as the
ÿ Very low standby current (15µA typical)
wide temperature range make the IC interesting for a wide field
