ADM489ARZ-REEL7集成電路（IC）的驅(qū)動器接收器收發(fā)器規(guī)格書PDF中文資料

ADM489ARZ-REEL7屬于集成電路（IC）的驅(qū)動器接收器收發(fā)器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADM489ARZ-REEL7驅(qū)動器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進行通信。確切的功能會因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對于通信用途可能并非絕對必要，但對于可能的使用環(huán)境卻是明智之選。

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.
