Automotive ISO 9141 Serial Link
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.
Features
• Electrically Compatible with Specification “Diagnosis System
ISO9141”
• Transmission speed up to 200kBaud
• Internal Voltage Reference Generator 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
• Pb-Free Packaging Designated by Suffix Code EF
LIN, ISO-9141 J-1850 PHYSICAL

Table 3. Static Electrical Characteristics
Characteristics noted under conditions VCC from 4.5V to 5.5V, VS from 4.5V to 20V unless otherwise note. Typical values
reflect approximate mean at 25°C, nominal VCC and VS, at time of device characterization. Typical values noted reflect the
approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
