ADM487EARZ-REEL7集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ADM487EARZ-REEL7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ADM487EARZ-REEL7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 ADM485E/ADM487E/ADM1487E are 5 V, low power data transceivers with ±15 kV ESD protection suitable for half duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with Telecommunication Industry Association/Electronics Industries Association (TIA/EIA) standards RS-485 and RS-422. The ADM487E and ADM1487E have a 1/4 unit load receiver input impedance that allows up to 128 transceivers on a bus, whereas the ADM485E allows up to 32 transceivers on a bus. Because only one driver is enabled at any time, the output of a disabled or power-down driver is three-stated to avoid overloading the bus.
