Serial Link Driver

The MC33199D is a serial interface circuit used in diagnostic applica-

tions. 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 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 MC33199D has a unique feature which allow transmission Baud rate

up to 200kBauds.

• Electrically Compatible with Specification “Diagnosis System ISO9141”

• Transmission speed up to 200kBauds

• Internal Voltage Reference Genarator for Line Comparator Thresholds

• Txd, Rxd and LO pins are 5V CMOS Compatible

• High Current Capability of DIA pin (K line)

• Short Circuit Protection for the K Line Input

• Over Temperature Shutdown with Hysteresis

• Large Operating Range of Driver Supply Voltage

• Large Operating Temperature Range

• ESD Protected pins
