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.

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.

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.

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

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.

Transmitter (Driver) Section  
HIGH BAUD RATE  
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.  
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.  
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.
