Driver
33199
The MC33199 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 MC33199 has
been designed to meet the «Diagnosis System ISO9141»
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 allow transmission Baud
rate up to 200kBaud.
