The ADM3101E transceiver is a high speed, single-channel RS-
232/V.28 interface devices that operate from a single 3.3 V
power supply. Low power consumption make it ideal for
battery-powered portable instruments.
The ADM3101E conforms to the EIA-232E and CCITT V.28
specifications and operates at data rates 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). 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 being
plugged/unplugged with the ±15kV ESD protection of the
ADM3101E’s I/O 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 ADM3101E is available in a 12-lead LFCSP.
