Description

The U6812B is a bipolar monolithic K-line bus transceiver designed to provide bi-directional serial communication in automotive diagnostic applications. The standard K-line is ISO 9141 compatible for baud rates up to 250 kBaud.

The IC provides three universally applicable 40-mA open-collector buffers, that can be used for signal decoupling. The U6812B is manufactured using Atmel's bipolar process and fully complies to automotive industry specifications.The U6812B provides an ideal grouping of SO-packaged low-power drivers, thus meeting customers' demand for space-saving and cost-effective circuit board assembly.
