Product DetailsThe ADM202E and ADM1181A are robust, high speed, 2- channel RS232/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.
The ADM202E provides a robust pin-compatible upgrade for existing ADM202, ADM232L or MAX202E/MAX232E sockets. It is available in a 16-pin DIP, wide and narrow SO and also a space saving TSSOP package. The TSSOP package gives a 44% space saving over SOIC.
The ADM1181A provides a robust pin compatible upgrade for the LTC1181A, and it is available in 16-pin DIP and 16-lead SO packages.
