GENERAL DESCRIPTION
The ADM202E 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 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.

Figure 2.
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.
