DESCRIPTION
The IC is designed for communication via bidirectional serial data channels. In addition to the level conversion of transmit and receive signals from the micro processor’s voltage level to the 12V bus level, the device includes plausibility checks in order to guarantee undisturbed bus communication in case of corrupted data from the micro controller.
