MC33790中文资料摩托罗拉数据手册PDF规格书

The 33790 is a two-channel physical layer interface IC for the Distributed System Interface (DSI) bus. It is designed to meet automotive requirements. It can also be used in nonautomotive applications. It supports bidirectional communication between slave and masterICs. Some slave devices derive a regulated 5.0 V from the bus, which can be used to power sensors, there by

eliminating the need for additional circuitry and wiring.
