MC33290

The MC33290 is designed as a serial link bus interface device designed to provide bidirectional halfduplex communication interfacing in automotive diagnostic applications.

MC33290 has eleven features. (1)Designed to operate over wide supply voltage of 8.0 to 18V. (2)Ambient operating temperature of -40°C to 125°C. (3)Interfaces directly to standard CMOS microprocessors. (4)ISO K line pin protected against shorts to ground. (5)Thermal shutdown with hysteresis. (6)Maximum transmission speeds in excess of 50k baud. (7)ISO K line pin capable of high currents. (8)ISO K line can be driven with up to 10nF of parasitic capacitance. (9)8.0kV ESD protection attainable with few additional components. (10)Standby mode: no Vbat current drain with Vdd at 5.0V. (11)Low current drain during operation with Vdd at 5.0V. Those are all the main features.

Some absolute maximum ratings of MC33290 have been concluded into several points as follow. (1)Its Vdd DC supply voltage would be from -0.3V to 7V. (2)Its Vbb load dump peak voltage would be 45V. (3)Its ISO pin load dump peak voltage would be 40V. (4)tsISO short circuit current limit would be 1.0A. (5)Its ESD voltage would be 2000V for human body model and would be 200V for machine model. (6)Its ISO clamp energy would be 10mJ. (7)Its storage temperature range would be from -55°C to 150°C. (8)Its operating case temperature range would be from -40°C to 125°C. (9)ts operating junction temperature range would be from -40°C to 150°C. (10)Its power dissipation would be 0.8W. (11)ts soldering temperature for 10 seconds would be 260°C. (12)Its thermal resistance (junction to ambient) would be 150°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical chaacteristics are concluded as follow. (1)Its Vdd sleep state current would be max 0.1mA. (2)Its Vdd quiescent operating current would be max 1.0mA. (3)Its input high voltage threshold would be min 0.7Vdd. (4)Its input low voltage threshold would be max 0.3Vdd. And so on.
