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 EU directive 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.
