GENERAL DESCRIPTION
The ADM3232E transceiver is a high speed, 2-channel RS-232/V.28
interface device that operates from a single 3.3 V power supply.
Low power consumption makes it ideal for battery-powered
portable instruments. The ADM3232E conforms to the EIA-232E
and ITU-T V.28 specifications and operates at data rates up to
460 kbps.
All RS-232 (Tx
against electrostatic discharges (up to ±15 kV ESD protection).
This ensures compliance with IEC 1000-4-2 requirements.
This device is ideally suited for operation in electrically harsh
environments or where RS-232 cables are frequently plugged/
unplugged, with the ±15 kV ESD protection of the ADM3232E
RS-232 input/output pins.

Emissions are also controlled to within very strict limits. CMOS
technology is used to keep the power dissipation to an absolute
minimum, allowing maximum battery life in portable applications.
Four external 0.1 μF charge pump capacitors are used for the
voltage doubler/inverter, permitting operation from a single
3.3 V supply.
The ADM3232E is available in a 16-lead narrow and wide SOIC
packages, as well as a space-saving 16-lead TSSOP.
