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

NOTES: 1. Measured with TXD = VCC, I1 = VS, DIA and L high, no load. REF–IN–L and REF–IN–K connected to REF–OUT .

2.0 < VCC < 5.5 V, 0 < VS < 40 V, 0 < V

3.When an over temperature is detected, the DIA output is forced “off”.

4.0 < VCC < 5.5 V, 0 < VS < 40 V, 0 < VL < 20 V.

5.At static “High” or “Low” level TXD, the current source I1 delivers a current of 3.0 mA (typ). Only during “Low” to “High” transition, does this current
increase to a higher value in order to charge the K Line capacitor (CL < 4.0 nF) in a short time (see Figure 3).
