FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
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 of15 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.
The ADM2209E conforms to the EIA-232E and CCITT V.28
specifications and operates at data rates up to 460 kbps.
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 is available in a 38-lead TSSOP package.

NOTESAll typicals are given for VDD = +12 V, VSTBY = 5 V, TA = +25°C.Current into device pins is defined as positive. Current out-of-device pins is defined as negative. All voltages are referred to ground unless otherwise specified. For
current, minimum and maximum values are specified as an absolute value and the sign is used to indicate direction. For voltage logic levels, the more positive value is
designated as maximum. For example, if –6 V is a maximum, the typical value (–6.8 V) is more negative.
