ADM489ARU集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ADM489ARU属于集成电路（IC）的驱动器接收器收发器。由亚德诺半导体技术有限公司制造生产的ADM489ARU驱动器，接收器，收发器该系列产品的主要功能是提供必需的硬件资源，以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异，可能包括诸如瞬态抑制之类的功能，这些功能对于通信用途可能并非绝对必要，但对于可能的使用环境却是明智之选。

GENERAL DESCRIPTION

The ADM488 and ADM489 are low power, differential line transceivers suitable for communication on multipoint bus transmission lines. They are intended for balanced data transmission and comply with both Electronics Industries Association (EIA) RS-485 and RS-422 standards. Both products contain a single differential line driver and a single differential line receiver, making them suitable for full-duplex data transfer. The ADM489 contains an additional receiver and driver enable control.
