MC33660BEF

MC33660BEF is an ISO K line serial link interface. It 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 over-temperature conditions. The 33660 derives its robustness to temperature and voltage extremes by being built on a SMARTMOS process, incorporating CMOS logic, bipolar/MOS analog circuitry, and DMOS power FETs. Application includes farm equipment, automotive systems, industrial equipment, robotic equipment, applications where module-to-module communications are required, marine and aircraft networks.
