GENERAL DESCRIPTION
The ADM2xxE is a family of robust RS-232 and V.28 interface
devices that operate 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 electromagnetic
compatibility (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 (IEC 1000-4-2),
fast transient burst protection (IEC 100044), and radiated
immunity (IEC 1000-4-3). EM emissions include radiated and
conducted emissions as required by Information Technology
Equipment EN 55022, CISPR 22.
All devices fully conform to the EIA-232-E 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 (see
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
capacitors are required.
The ADM207E and ADM208E are available in 24-lead PDIP, SSOP,
available in 28-lead SSOP, TSSOP, and SOIC_W packages. All
products are backward compatible with earlier ADM2xx products,
facilitating easy upgrading of older designs.
