Automotive ISO 9141
Serial Link Driver
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.
• Electrically Compatible with Specification “Diagnosis System ISO 9141”
• Transmission Speed Up to 200 k Baud
• Internal Voltage Reference Generator for Line Comparator Thresholds
• TXD, RXD and LO Pins are 5.0 V 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
• Full Operating Temperature Range
• ESD Protected Pins
