RS-232接口是目前最常用(yòng)的一种串行通讯接口。它是在1970年由美國(guó)電(diàn)子工(gōng)业协会(EIA)联合贝尔系统、调制解调器厂家及计算机终端生产(chǎn)厂家共同制定的用(yòng)于串行通讯的标准。它的全名(míng)是“数据终端设备(DTE)和数据通讯设备(DCE)之间串行二进制数据交换接口技(jì )术标准”该标准规定采用(yòng)一个25个脚的DB-25连接器，对连接器的每个引脚的信号内容加以规定，还对各种信号的電(diàn)平加以规定。后来IBM的PC机将RS232简化成了DB-9连接器，从而成為(wèi)事实标准。而工(gōng)业控制的RS-232口一般只使用(yòng)RXD、TXD、GND三条線(xiàn)。
从传统的RS232收发器到具(jù)备Auto On-line Plus特性的更為(wèi)先进的RS232产(chǎn)品，MxL提供40多(duō)种RS232串行收发器。此外，多(duō)种的RS232收发器均具(jù)备经过改进的ESD保护技(jì )术。MxL提供能(néng)搞满足严格的IEC 61000-4-2 Air-Gap和接触型ESD标准的新(xīn)型RS232产(chǎn)品。这种保护功能(néng)使产(chǎn)品不会因ESD而遭受损害。许多(duō)此类产(chǎn)品均為(wèi)现有(yǒu)的工(gōng)业标准解决方案的直接替代产(chǎn)品与功能(néng)对等产(chǎn)品。
