                The MC33199D is a serial interface circuit used in diagnostic
                applications. It is the interface between the microcontroller and the special
                K and L Lines of the ISO diagnostic port. The MC33199D has been
                designed to meet the “Diagnosis System ISO 9141” specification.
                The device has a bi–directional bus K Line driver, fully protected against
                short circuits and over temperature. It also includes the L Line receiver,
                used during the wake up sequence in the ISO transmission.
                The MC33199 has a unique feature which allows transmission baud rate
                up to 200 k baud.
