GENERAL DESCRIPTION
The ADM2xxE is a family of robust RS-232 and V.28 interface
devices that operates from a single 5 V power supply. These products are suitable for operation in harsh electrical environments
and are compliant with the EU directive on EMC (89/336/EEC).
The level of emissions and immunity are both in compliance.
EM immunity includes ESD protection in excess of ±15 kV on all
I-O lines (1000-4-2), 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.
All devices fully conform to the EIA-232E and CCITT V.28
specifications and operate at data rates up to 230 kbps.
Shutdown and Enable control pins are provided on some of the
products. Please refer to Table I.
The shutdown function on the ADM211E disables the charge
pump and all transmitters and receivers. On the ADM213E the
charge pump, all transmitters, and three of the five receivers are
disabled. The remaining two receivers remain active, thereby
allowing monitoring of peripheral devices. This feature allows
the device to be shut down until a peripheral device begins
communication. The active receivers can alert the processor
which can then take the ADM213E out of the shutdown mode.
Operating from a single 5 V supply, four external 0.1 µF capaci-
tors are required.
The ADM207E and ADM208E are available in 24-lead DIP,
SO, SSOP and TSSOP packages. The ADM211E and ADM213E
are available in 28-lead SO, SSOP and TSSOP packages.
All products are backward-compatible with earlier ADM2xx
products, facilitating easy upgrading of older designs.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADM206E/ADM207E/ADM208E/ADM211E/ADM213E features proprietary ESD protection
circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges.
Therefore, proper ESD precautions are recommended to avoid performance degradation or loss
of functionality.
