PULL-DOWN RESIST OR ON EACH RS-232 INPUT.  
The ADM2xx family of line drivers/receivers is intended for all  
EIA-232-E and V.28 communications interfaces, especially in  
applications where ±±2 V is not available. The ADM206,  
ADM2±±, and ADM2±3 feature a low power shutdown mode  
that reduces power dissipation to less than 5 µW, making them  
ideally suited for battery-powered equipment. The ADM2±3  
has an active low shutdown and an active high receiver-enable  
control. Two receivers of the ADM2±3 remain active during  
shutdown. This feature is useful for ring indicator monitoring.  
Figure 1.  
All members of the ADM2xx family, except the ADM209,  
include two internal charge pump voltage converters that allow  
operation from a single 5 V supply. These parts convert the 5 V  
input power to the ±±0 V required for ꢀR-232 output levels.  
The ADM209 is designed to operate from 5 V and ±2 V supplies.  
An internal +±2 V to –±2 V charge pump voltage converter  
generates the –±2 V supply.

Table 3.  
Rtresses above those listed under Absolute Maximum ꢀatings  
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  
sections of this specification is not implied. Exposure to  
absolute maximum rating conditions for extended periods of  
time 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 INFORMATION

C2  
C4  
S4  
The ADM206–ADM2±±/ADM2±3 family of ꢀR-232 drivers/  
receivers is designed to solve interface problems by meeting the  
EIA-232-E specifications while using a single digital 5 V supply.  
The EIA-232-E standard requires transmitters that will deliver  
±5 V minimum on the transmission channel and receivers that  
can accept signal levels down to ±3 V. The ADM206–ADM2±±/  
ADM2±3 meet these requirements by integrating step-up voltage  
converters and level shifting transmitters and receivers onto the  
same chip. CMOR technology is used to keep the power dissi-  
pation to an absolute minimum. A comprehensive range of  
transmitter/receiver combinations is available to cover most  
communication needs. The ADM206–ADM2±±/ADM2±3 are  
modifications, enhancements, and improvements to the AD230–  
AD24± family and derivatives thereof. They are essentially plug-  
in compatible and do not have materially different applications.

Capacitors C3 and C4 are used to reduce the output ripple.  
Their values are not critical and can be reduced if higher levels  
of ripple are acceptable. The charge pump capacitors C± and C2  
may also be reduced at the expense of higher output impedance  
on the V+ and V– supplies.  
The V+ and V– supplies may also be used to power external  
circuitry if the current requirements are small.  
Transmitters (Drivers)  
The drivers convert TTL/CMOR input levels into EIA-232-E  
output levels. With VCC = +5 V and driving a typical EIA-232-E  
load, the output voltage swing is ±9 V. Even under worst-case  
conditions, the drivers are guaranteed to meet the ±5 V EIA-  
232-E minimum requirement.  
The ADM206, ADM2±±, and ADM2±3 are particularly useful in  
battery-powered systems because they feature a low power shut-  
down mode that reduces power dissipation to less than 5 µW.  
The ADM209 includes only a negative charge pump converter  
and is intended for applications where a +±2 V is available.  
The input threshold levels are both TTL- and CMOR-compatible  
with the switching threshold set at VCC/4. With a nominal VCC  
5 V, the switching threshold is ±.25 V typical. Unused inputs  
may be left unconnected, because an internal 400 kΩ pull-up  
resistor pulls them high, forcing the outputs into a low state.  
=
To facilitate sharing a common line or for connection to a  
microprocessor data bus, the ADM206, the ADM209, the  
ADM2±±, and the ADM2±3 feature an enable ( ) function.  
EN  
When the receivers are disabled, their outputs are placed in a  
high impedance state.  
As required by the EIA-232-E standard, the slew rate is limited  
to less than 30 V/µs, without the need for an external slew  
limiting capacitor, and the output impedance in the power-off  
state is greater than 300 Ω.  
CIRCUIT DESCRIPTION  
The internal circuitry in the ADM206–ADM2±±/ADM2±3  
consists of three main sections: (a) a charge pump voltage  
converter; (b) ꢀR-232-to-TTL/CMOR receivers; and  
(c) TTL/CMOR-to-ꢀR-232 transmitters.  
Receivers  
The receivers are inverting level shifters that accept EIA-232-E  
input levels (±5 V to ±±5 V) and translate them into 5 V TTL/  
CMOR levels. The inputs have internal 5 kΩ pull-down resistors  
to ground and are also protected against overvoltages of up to  
±30 V. The guaranteed switching thresholds are 0.8 V minimum  
and 2.4 V maximum, well within the ±3 V EIA-232-E require-  
ment. The low level threshold is deliberately positive, since it  
ensures that an unconnected input will be interpreted as a  
low level.  
Charge Pump DC-to-DC Voltage Converter  
The charge pump voltage converter consists of an oscillator and  
a switching matrix. The converter generates a ±±0 V supply  
from the 5 V input. This is done in two stages using a switched  
capacitor technique, as illustrated in Figure 22 and Figure 23.  
First, the 5 V input supply is doubled to ±0 V using capacitor  
C± as the charge storage element. The ±0 V level is then  
inverted to generate –±0 V using C2 as the storage element.  
The receivers have Rchmitt-trigger inputs with a hysteresis level  
of 0.65 V. This ensures error-free reception for both noisy  
inputs and inputs with slow transition times.

Shutdown (SD)  
The ADM206–ADM2±±/ADM2±3 feature a control input that  
may be used to disable the part and reduce the power consump-  
ion to less than 5 ΩW. This is very useful in battery-operated  
systems. During shutdown, the charge pump is turned off, the  
transmitters are disabled, and all receivers except ꢀ4 and ꢀ5 on  
the ADM2±3 are put into a high impedance disabled state.

ADM206–ADM211/ADM213  
ꢀeceivers ꢀ4 and ꢀ5 on the ADM2±3 remain enabled during  
shutdown. This feature allows monitoring external activity  
while the device is in a low power shutdown mode. The  
shutdown control input is active high on all parts except the  
ADM2±3, where it is active low. Ree Table 5 and Table 6.  
APPLICATION HINTS  
Driving Long Cables  
In accordance with the EIA-232-E standard, long cables are  
permissible provided the total load capacitance does not exceed  
2500 pF. For longer cables that do exceed this, it is possible to  
trade off baud rate for cable length. Large load capacitances cause  
a reduction in slew rate, and therefore the maximum transmis-  
sion baud rate is decreased. The ADM206–ADM2±±/ADM2±3  
are designed to minimize the slew rate reduction that occurs as  
load capacitance increases.  
Enable Input  
The ADM209, ADM2±±, and ADM2±3 feature an enable input  
used to enable or disable the receiver outputs. The enable input  
is active low on the ADM209 and ADM2±± and active high on  
the ADM2±3. Ree Table 5 and Table 6. When the receivers are  
disabled, their outputs are placed in a high impedance state.  
This function allows the outputs to be connected directly to a  
microprocessor data bus. It can also be used to allow receivers  
from different devices to share a common data line. The timing  
diagram for the enable function is shown in Figure 24.  
For the receivers, it is important that a high level of noise  
immunity be inbuilt so that slow rise and fall times do not  
cause multiple output transitions as the signal passes slowly  
through the transition region. The ADM206–ADM2±±/  
ADM2±3 have 0.65 V of hysteresis to guard against this. This  
ensures that even in noisy environments error-free reception  
can be achieved.
