The RS-232 specification allows for reliable data transmission from one transmitter to one receiver at data rates of up to 20K bits/second over relatively short distances (up to 50 feet). On more recent RS-232 Transceiver chips, data rates of up to 1Mbps are achievable over shorter distances (up to 5 feet). The most common applications for RS-232 Transceivers are computers and peripherals, mobile phone data cables and diagnostic data ports. Analog Devices offers a wide range of RS-232 Transceivers to suit many applications.
