ST232ACD集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器規(guī)格書(shū)PDF中文資料

ST232ACD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ST232ACD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(guò)延長(zhǎng)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(lèi)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。

Description

The ST232A is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications where ±12V is not available. The ST232A uses a single 5V power supply and only four external capacitors (0.1μF). Typical applications are in: Portable Computers, Low Power Modems, Interfaces Translation, Battery Powered RS-232 Networks.
