installation of an interface cable. To prevent ESD damage, Maxim's interface ICs incorporate "ESD structures." The ESD structures protect the transmitter outputs, receiver inputs, digital interface connections, and analog connections to the RS-422/RS-485 transceivers against ESD levels up to ±...
Interface Circuits for TIA / EIA-485
Abstract: Electrical specifications are presented for the RS-422 unidirectional, RS-485 full-duplex and PROFIBUS data transmission systems. Electrostatic discharge (ESD) protection, data rates, and loading conditions are considered. The co...

Electrical Characteristics of Balanced Voltage Digital Interface Circuits ANSI/TIA/EIA 422-B-1994 发布历史 ANSI/TIA/EIA 422-B-1994由美国国家标准学会 US-ANSI 发布于 1994。 ANSI/TIA/EIA 422-B-1994 在中国标准分类中归属于: M14 通信网传输系统接口,在国际标准分类中归属于: 35.200 接口和互连设备。
接口之一。而RS-422接口,标准全称是“平衡电压数字接口电路的电气特性”,它定义了接口电路的特性。典型的RS-422是四线接口。实际上还有一根信号地线,共5根线。其DB9连接器引脚定义。RS-485接口是从RS-422基础上发展而来的,所以RS-485许多电气规定与RS-422相仿。 PS/2......
