ADM202EARN Datasheet

RS-232 Interface IC


The ADM202EARN 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 operationin 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 immunityincludes 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.The ADM202E provides a robust pin-compatible upgrade for existing ADM202, ADM232L, or MAX202E/MAX232E sockets. It is available in a 16-lead PDIP, a wide SOIC, a narrow SOIC, and a space-saving TSSOP package that is 44% smaller than the SOIC package. The ADM1181A provides a robust pin-compatible upgrade for the LTC1181A, and it is available in a 16-lead PDIP package and a wide 16-lead SOIC package.
