The ADM202E and ADM1181A are robust, high speed,2-channel RS-232/V.28 interface devices that operate from a single 5 V power supply. Both products are suitable for operation in harsh electrical environments and are compliant with the EUdirective on EMC (89/336/EEC). Both the level of electromagnetic emissions and immunity are in compliance. EM immunity includes ESD protection in excess of ±15 kV on all I/O lines,fast transient/burst protection (1000-4-4), and radiated immunity (1000-4-3). EM emissions include radiated and conducted emissions as required by Information Technology Equipment EN55022, CISPR22.The ADM202E and ADM1181A conform to the EIA-232E and CCITT V.28 specifications and operate at data rates up to 230 kbps.Four external 0.1 μF charge-pump capacitors are used for the voltage doubler/inverter, permitting operation from a single 5 V supply.
