RS-232 / RS-422 / RS-485 / RS-562

Analog Devices offers a wide range of RS-232, RS-422, RS-485, and RS-562 transceivers to suit applications for nonisolated interfaces, as well as digital isolation requirements using iCoupler® technology. The RS-232 specification allows for reliable data transmission from one transmitter to one receiver at data rates of up to 20 kbps over distances of up to 50 feet, or up to 1 Mbps over distances of up to 5 feet for more recent RS-232 transceiver chips. While similar to RS-232, the RS-562 standard differs by specifying a minimum driver output voltage of ±3.7 V to ease power supply requirements. The RS-485 specification meets the requirements for a truly multipoint communications network, while the RS-422 specification satisfies simplex multidrop standards.
