L9637D集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書PDF中文資料

L9637D屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的L9637D驅(qū)動(dòng)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(jìn)行通信。確切的功能會(huì)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(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。
