SP208E, SP211E, SP213E Low Power, High ESD +5V RS-232 Transceivers Data Sheet EIA Standards The RS-232 is a relatively slow data exchange protocol, EIA Standards with a maximum baud rate of only 20kbps, which can be transmitted over a maximum copper wire cable length of 50 The Electronic Industry Association (EIA) developed feet. The SP208E, SP211E and SP213E data several standards of data transmission which are revised communications interface products have been designed to and updated in order to meet the requirements of the meet both the EIA protocol standards, and the needs of the industry. In data processing, there are two basic means of industry. communicating between systems and components. The RS-232 standard was first introduced in 1962 and, since Table 6: Transceiver ESD Tolerance Levels that time, has become an industry standard.
