RS-232接口是目前最常用的一种串行通讯接口。它是在1970年由美国电子工业协会(EIA)联合贝尔系统、调制解调器厂家及计算机终端生产厂家共同制定的用于串行通讯的标准。它的全名是“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术标准”该标准规定采用一个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，还对各种信号的电平加以规定。后来IBM的PC机将RS232简化成了DB-9连接器，从而成为事实标准。而工业控制的RS-232口一般只使用RXD、TXD、GND三条线。
从传统的RS232收发器到具备Auto On-line Plus特性的更为先进的RS232产品，MxL提供40多种RS232串行收发器。此外，多种的RS232收发器均具备经过改进的ESD保护技术。MxL提供能搞满足严格的IEC 61000-4-2 Air-Gap和接触型ESD标准的新型RS232产品。这种保护功能使产品不会因ESD而遭受损害。许多此类产品均为现有的工业标准解决方案的直接替代产品与功能对等产品。
