Designed to interface between the vehicle’s on-board microcontroller and the system’s off-board microcontroller in the vehicle via the special ISO K line, the device meets the Diagnostic Systems ISO9141 specification. It is the SMARTMOS 8, direct pin-to-pin replacement device for the MC33290.
The 33660 is a serial link bus interface device designed to provide bi-directional half-duplex communication interfacing in automotive diagnostic applications. It is designed to interface between the vehicle’s on-board microcontroller and systems off-board the vehicle via the special ISO K line. The 33660 is designed to meet the Diagnostic Systems ISO9141 specification. The device’s K line bus driver’s output is fully protected against bus shorts and overtemperature conditions.
