ADM2209EARUZ

ADM2209E is a complete, dual RS-232 port on a single chip, containing six drivers and ten receivers and fully meeting EIA-232 and V.28 specifications. It features an onboard DC to DC converter to generate a -12V power rail, eliminating the need for a negative power supply. It is suitable for operation in harsh electrical environments and is compliant with the EU directive on EMC (89/336/EEC). Both the level of emissions and immunity are in compliance. EM immunity includes ESD protection in excess of ±15KV on all I-O lines (1000-4-2), Electrical Fast Transient 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. It is widely used in application such as personal computers, printers, peripherals, modems etc.
