GENERAL DESCRIPTION
The ADM3101E is a high speed, single-channel, RS-232/
ITU-T V.28 transceiver interface device that operates from
a single 3.3 V power supply. Low power consumption makes
it ideal for battery-powered portable instruments.
The ADM3101E conforms to the EIA/TIA-232E and ITU-T V.28
specifications and operates at data rates of up to 460 kbps.
All RS-232 (T
OUT
and R
IN
) and CMOS (T
IN
and R
OUT
) inputs
and outputs are protected against electrostatic discharges (up
to ±15 kV ESD protection).
Because of the ±15 kV ESD protection of the ADM3101E
input/output pins, this device is ideally suited for operation
in electrically harsh environments or where RS-232 cables are
frequently plugged and unplugged.
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 ADM3101E is available in both a 12-lead LFCSP and 16-lead
QSOP, specified over the −40°C to +85°C temperature range.
