NXP Semiconductors Interface - Interface - Specialized - MC33660BEFR2 MC33660BEFR2

The MC33660BEFR2 is a serial link bus interface device designed for bi-directional half-duplex communication in automotive diagnostic applications, compliant with the ISO9141 specification. It interfaces between a vehicle's on-board microcontroller and off-board systems via the ISO K line. The device operates over a supply voltage range of 8.0 V to 18 V and is specified for an ambient temperature range of -40 ¬8C to 125 ¬8C. Key features include robust protection against bus shorts and over-temperature conditions, thermal shutdown with hysteresis, and the ability to drive high currents on the ISO K line. The device supports parasitic capacitance of up to 10 nF and offers 8.0 kV ESD protection with minimal additional components. It is packaged in an economical SO-8 surface-mount plastic package, making it suitable for various applications beyond automotive, including industrial and robotic equipment.
