ST3222CTR集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ST3222CTR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ST3222CTR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 ST3222 is a 3 V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements and high data-rate capabilities. ST3222 has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 3.6 V power supplies. The device requires only four small 0.1 mF standard external capacitors for operating from 3 V supply. The ST3222 has two receivers and two drivers. The ST3222 features a 1 mA shutdown mode that reduces power consumption and extends battery life in portable systems.
