描述 Description

The ST232AB/AC is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications where ±12 V is not available. The ST232AB/AC uses a single 5 V power supply and only four external capacitors (0.1 μF). Typical applications are in: portable computers, low power modems, interfaces translation, battery powered RS-232 networks.

簡介

ST232AB屬于集成電路（IC）的驅動器接收器收發(fā)器。由制造生產(chǎn)的ST232AB驅動器，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。
