ST232A集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ST232A属于集成电路（IC）的驱动器接收器收发器。由意法半导体集团制造生产的ST232A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。

描述 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.
