MAX202-MAX211
+5V RS-232 Transceivers with 0.1µF External Capacitors. Maxim has incorporated many new features into the RS-232 components that provide engineering value.
General Description
MAX200-MAX209, MAX211, and MAX213 are a family
of RS-232 and V.28 transceivers with integrated charge
pump circuitry for single +5V supply operation.
The drivers maintain the ±5V EIA/TIA-232E output signal
levels at data rates in excess of 120kbps when loaded in
accordance with the EIA/TIA-232E specification.
The MAX211 and MAX213 are available in a 28-pin, wide
small-outline (SO) package and a 28-pin shrink small-
outline (SSOP) package, which occupies only 40% of the
area of the SO. The MAX207 is available in a 24-pin SO
package and a 24-pin SSOP. The MAX203 and MAX205
use no external components and are recommended for
applications with limited circuit board space.

Typical Operating Characteristics
Detailed Description
The MAX200–MAX209/MAX211/MAX213 consist of three
sections: charge-pump voltage converters, drivers (trans-
mitters), and receivers. Each section is described in detail.
+5V to ±10V Dual Charge-Pump
Voltage Converter
The +5V to ±10V conversion is performed by two charge-
pump voltage converters (Figure 4). The first uses capaci-
tor C1 to double +5V to +10V, storing +10V on the V+
output filter capacitor, C3. The second chargepump volt-
age converter uses capacitor C2 to invert +10V to -10V,
storing -10V on the V- output filter capacitor, C4.
The MAX201 and MAX209 include only the V+ to Vcharge
pump, and are intended for applications that have a VCC
= +5V supply and a V+ supply in the +9V to +13.2V range.
In shutdown mode, V+ is internally connected to VCC by a 1kΩ pulldown resistor and V- is internally connected to ground by a 1kΩ pullup resistor.
RS-232 Drivers
When VCC = +5V, the typical driver output-voltage swing is ±8V when loaded with a nominal 5kΩ RS-232 receiver.
The output swing is guaranteed to meet the EIA/TIA-232E
and V.28 specifications, which call for ±5V minimum out-
put levels under worst-case conditions. These include a minimum 3kΩ load, VCC = +4.5V, and the maximum
operating temperature. The open-circuit output-voltage
swing ranges from (V+ - 0.6V) to V-.
Input thresholds are both CMOS and TTL compatible. The
inputs of unused drivers can be left unconnected since 400kΩ pullup resistors to VCC are included onchip. Since
all drivers invert, the pullup resistors force the outputs of
unused drivers low. The input pullup resistors typically source 15μA; therefore, the driver inputs should be driven
high or open circuited to minimize power-supply current
in shutdown mode.
When in low-power shutdown mode, the driver outputs
are turned off and their leakage current is less than 1mA,
even if the transmitter output is backdriven between 0V
and (VCC + 6V). Below -0.5V, the transmitter output is diode clamped to ground with a 1kΩ series impedance.
The transmitter output is also zener clamped to approxi-
mately (VCC + 6V), with a 1kΩ series impedance.

RS-232 Receivers
The receivers convert RS-232 signals to CMOS logic
output levels. Receiver outputs are inverting, maintaining
compatibility with driver outputs. The guaranteed receiver
input thresholds of +0.8V and +2.4V are significantly
tighter than the ±3.0V threshold required by the EIA/TIA-
232E specification. This allows receiver inputs to respond
to TTL/CMOS logic levels and improves noise margin for
RS-232 levels.
The MAX200–MAX209/MAX211/MAX213 guaranteed
+0.8V threshold (+0.6V in shutdown for the MAX213)
ensures that receivers shorted to ground have a logic 1 output. Also, the 5kΩ input resistance to ground ensures
that a receiver with its input left open also has a logic 1
output.
Receiver inputs have approximately +0.5V hysteresis.
This provides clean output transitions, even with slow rise
and fall time input signals with moderate amounts of noise

Shutdown and Enable Control
In shutdown mode, the MAX200/MAX205/MAX206/
MAX211/MAX213 charge pumps are turned off, V+ is
pulled down to VCC, V- is pulled to ground, and the trans-
mitter outputs are disabled. This reduces supply current
typically to 1μA (15μA for the MAX213). The time required
to exit shutdown is 1ms, as shown in Figure 5.
All receivers except R4 and R5 on the MAX213 are put
into a high-impedance state in shutdown mode. The
MAX213’s R4 and R5 receivers still function in shutdown
mode. These two receivers are useful for monitoring
external activity while maintaining minimal power con-
sumption.
The enable control is used to put the receiver outputs into
a high-impedance state, so that the receivers can be con-
nected directly to a three-state bus. It has no effect on the
RS-232 drivers or on the charge pumps.
MAX213 Receiver Operation in Shutdown
During normal operation, the MAX213’s receiver propa-gation delay is typically 1µs. When entering shutdown
with receivers active, R4 and R5 are not valid until 80µs
after SHDN is driven low. In shutdown mode, propagation
delays increase to 4µs for a high-to-low or a low-to-high
transition.
When exiting shutdown, all receiver outputs are invalid
until the charge pumps reach nominal values (< 2ms
when using 0.1µF capacitors).

Applications Information
Capacitor Selection
The type of capacitor used is not critical for proper
operation. Ceramic capacitors are suggested. To ensure
proper RS-232 signal levels over temperature when
using 0.1µF capacitors, make sure the capacitance value
does not degrade excessively as the temperature varies.
If in doubt, use capacitors with a larger nominal value.
Also observe the capacitors’ ESR value over tempera-
ture, since it influences the amount of ripple on V+ and
V-. To reduce the output impedance at V+ and V-, use
larger capacitors (up to 10µF). If polarized capacitors are
used, obey the polarities shown in Figure 1 and the pin
configurations.
Driving Multiple Receivers
Each transmitter is designed to drive a single receiver.
Transmitters can be paralleled to drive multiple receivers.
Driver Outputs When Exiting Shutdown
Figure 5 shows two driver outputs exiting shutdown. As
they become active, the two driver outputs go to opposite
RS-232 levels (one driver input is high, the other is low). Each driver is loaded with 3kΩ in parallel with 2500pF.
The driver outputs display no ringing or undesirable tran-
sients as they come out of shutdown.
Power-Supply Decoupling
In applications that are sensitive to power-supply noise,
decouple VCC to ground with a capacitor of the same
value as the charge-pump capacitors.
V+ and V- as Power Supplies
A small amount of power can be drawn from V+ and V-,
although this reduces noise margins.
Power Supplies for MAX201/MAX209
If at power-up the V+ supply rises after the VCC supply,
place a diode (e.g., 1N914) in series with the V+ supply.
