GENERAL DESCRIPTION  
B
IN  
OUT  
The 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. The device features an on-  
board dc-to-dc converter to generate a –12 V power rail, elimi-  
nating the need for a negative power supply.

The ADM2209E 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  
±15 kV 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.  
R5  
In standby mode, one receiver on each port (R5) remains active  
to allow monitoring of peripheral devices while the rest of the  
system is in power-saving mode. This feature allows the  
ADM2209E to wake up the system when a peripheral device  
begins communication.  
The ADM2209E conforms to the EIA-232E and CCITT V.28  
specifications and operates at data rates up to 460 kbps.  
The ADM2209E is available in a 38-lead TSSOP package.
