MC33290D/R2中文资料飞思卡尔数据手册PDF规格书

The 33290 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 33290 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.
