GENERAL DESCRIPTION
The ADM3202/ADM3222/ADM1385 transceivers are high
speed, 2-channel RS-232/V.28 interface devices that operate
from a single 3.3 V power supply. Low power consumption and
a shutdown facility (ADM3222/ADM1385) make them ideal for
battery-powered portable instruments.
The ADM3202/ADM3222/ADM1385 parts conform to the
EIA-232E and CCITT V.28 specifications and operate at data
rates up to 460 kbps.
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 ADM3222 contains additional enable and shutdown
circuitry. The EN input can be used to three-state the receiver
outputs. The SD input is used to power down the charge pump
and transmitter outputs, reducing the quiescent current to less
than 0.5 μA. The receivers remain enabled during shutdown
unless disabled using EN.
The ADM1385 contains a driver disable mode and a complete
shutdown mode.
The ADM3202 is available in a 16-lead PDIP, SOIC_W, and
SOIC_N, as well as a space-saving 16-lead TSSOP. The ADM3222
is available in 18-lead PDIP and SOIC_W and in 20-lead SSOP
and TSSOP. The ADM1385 is available in a 20-lead SSOP,
which is pin-compatible with the LTC1385 CG.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD 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 this product 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.

GENERAL DESCRIPTION
The ADM3202/ADM3222/ADM1385 are RS-232 line drivers/
receivers. Step-up voltage converters coupled with level-shifting
transmitters and receivers allow RS-232 levels to be developed
while operating from a single 3.3 V supply.
CMOS technology is used to keep the power dissipation to an
absolute minimum, allowing maximum battery life in portable
applications.
The ADM3202/ADM3222/ADM1385 are modifications,
enhancements, and improvements of the AD230 to AD241
family and derivatives. They are essentially plug-in compatible
and do not have any materially different applications.
CIRCUIT DESCRIPTION
The internal circuitry consists of these main sections:
• A charge pump voltage converter
• 3.3 V logic to EIA-232 transmitters
• EIA-232 to 5 V logic receivers
Charge Pump DC to DC Voltage Converter
The charge pump voltage converter consists of a 200 kHz
oscillator and a switching matrix. The converter generates a
±6.6 V supply from the input 3.3 V level. This is done in two
stages by using a switched capacitor technique as illustrated in
Figure 18 and Figure 19. First, the 3.3 V input supply is doubled
to 6.6 V by using Capacitor C1 as the charge storage element.
The +6.6 V level is then inverted to generate −6.6 V using C2
as the storage element. C3 is shown connected between V+ and
VCC but is equally effective if connected between V+ and GND.
Capacitors C3 and C4 are used to reduce the output ripple.
Their values are not critical and can be increased, if desired.
Capacitor C3 is shown connected between V+ and VCC. It is
also acceptable to connect this capacitor between V+ and GND.
If desired, larger capacitors (up to 10 μF) can be used for
Capacitors C1 to C4.

Transmitter (Driver) Section
The drivers convert 3.3 V logic input levels into RS-232 output
levels. With VCC = 3.3 V and driving an RS-232 load, the output
voltage swing is typically ±6 V.
Receiver Section
The receivers are inverting level-shifters that accept RS-232
input levels and translate them into 3 V logic output levels. The
inputs have internal 5 kΩ, pull-down resistors to ground and are
protected against overvoltages up to ±30 V. Unconnected inputs
are pulled to 0 V by the internal 5 kΩ, pull-down resistor. This
results in a Logic 1 output level for unconnected inputs or for
inputs connected to GND.
The receivers have Schmitt-trigger inputs with a hysteresis level
of 0.4 V. This ensures error-free reception for both noisy inputs
and for inputs with slow transition times.
HIGH BAUD RATE
The ADM3202/ADM3222 feature high slew rates permitting
data transmission at rates well in excess of the EIA/RS-232E
specifications. RS-232 voltage levels are maintained at data rates
up to 460 kbps even under worst-case loading conditions. This
allows high speed data links between two terminals and is
suitable for the new generation ISDN modem standards that
require data rates of 230 kbps. The slew rate is internally
controlled to less than 30 V/μs to minimize EMI interference.
