U6812B General 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.

U6812B Maximum Ratings

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliabilit
