_______________Detailed Description
The MAX202E–MAX213E, MAX232E/MAX241E consist of
three sections: charge-pump voltage converters,
drivers (transmitters), and receivers. These E versions
provide extra protection against ESD. They survive
±15kV dischargesto the RS-232 inputs andoutputs,
testedusingthe Human Body Model. When tested
according to IEC1000-4-2, they survive ±8kV contact-
discharges and ±15kV air-gap discharges. The rugged
E versions are intended for use in harsh environments
or applications where the RS-232 connection is
frequently changed (such as notebook computers). The
standard (non-“E”) MAX202, MAX203, MAX205–
MAX208, MAX211, MAX213, MAX232, and MAX241 are
recommended for applications where cost is critical.
+5V to ±10V Dual Charge-Pump
Voltage Converter
The +5V to ±10V conversion is performed by dual
charge-pump voltage converters (Figure 4). The first
charge-pump converter uses capacitor C1 to double
the +5V into +10V, storing the +10V on the output filter
capacitor, C3. The second uses C2 to invert the +10V
into -10V, storing the -10V on the V- output filter
capacitor, C4.
In shutdown mode, V+ is internally connected to VCCby
a 1kΩpull-down resistor, and V- is internally connected
to ground by a 1kΩpull-up resistor.
RS-232 Drivers
With VCC= 5V, the typical driver output voltage swing
is ±8V when loaded with a nominal 5kΩRS-232
receiver. The output swing is guaranteed to meet
EIA/TIA-232E and V.28 specifications that call for ±5V
minimum output levels under worst-case conditions.
These include a 3kΩload, minimum VCC, and
maximum operating temperature. The open-circuit
output voltage swings from (V+ - 0.6V) to V-.
Input thresholds are CMOS/TTL compatible. The
unused drivers’ inputs on the MAX205E–MAX208E,
MAX211E, MAX213E, and MAX241E can be left
unconnected because 400kΩpull-up resistors to VCC
are included on-chip. Since all drivers invert, the pull-
up resistors force the unused drivers’ outputs low. The
MAX202E, MAX203E, and MAX232E do not have pull-
up resistors on the transmitter inputs.
MAX202E–MAX213E, MAX232E/MAX241E
±15kV ESD-Protected, +5V RS-232 Transceivers ______________________________________________________________________________________
When in low-power shutdown mode, the MAX205E/
MAX206E/MAX211E/MAX213E/MAX241E driver outputs
are turned off and draw only leakage currents—even if
they are back-driven with voltages between 0V and
12V. Below -0.5V in shutdown, the transmitter output is
diode-clamped to ground with a 1kΩseries
impedance.
RS-232 Receivers
The receivers convert the RS-232 signals to CMOS-logic
output levels. The guaranteed 0.8V and 2.4V receiver
input thresholds are significantly tighter than the ±3V
thresholds required by the EIA/TIA-232E specification.
This allows the receiver inputs torespond to TTL/CMOS-
logic levels, as well as RS-232 levels.
The guaranteed 0.8V input low threshold ensures that
receivers shorted to ground have a logic 1 output. The
5kΩinput resistance to ground ensures that a receiver
with its input left open will also have a logic 1 output.
Receiver inputs have approximately 0.5V hysteresis.
This provides clean output transitions, even with slow
rise/fall-time signals with moderate amounts of noise
and ringing.
In shutdown, the MAX213E’s R4 and R5 receivers have
no hysteresis.
Shutdown and Enable Control
(MAX205E/MAX206E/MAX211E/
MAX213E/MAX241E)
In shutdown mode, the charge pumps are turned off,
V+ is pulled down to VCC, V- is pulled to ground, and
the transmitter outputs are disabled. This reduces
supply current typically to 1µA (15µA for the MAX213E).
The time required to exit shutdown is under 1ms, as
shown in Figure 5.
Receivers
All MAX213E receivers, except R4 and R5, are put into
a high-impedance state in shutdown mode (see Tables
1a and 1b). The MAX213E’s R4 and R5 receivers still
function in shutdown mode. These two awake-in-
shutdown receivers can monitor external activity while
maintaining minimal power consumption.
The enable control is used to put the receiver outputs into
a high-impedance state, to allow wire-OR connection of
two EIA/TIA-232E ports (or ports of different types) at the
UART. It has no effect on the RS-232 drivers or the
charge pumps.
Note: The enable control pin is active low for the
MAX211E/MAX241E (EN), but is active high for the
MAX213E (EN). The shutdown control pin is active high
for the MAX205E/MAX206E/MAX211E/MAX241E
(SHDN), but is active low for the MAX213E (SHDN).

Configurations
The MAX213E’s receiver propagation delay is typically
0.5µs in normal operation. In shutdown mode,
propagation delay increases to 4µs for both rising and
falling transitions. The MAX213E’s receiver inputs have
approximately 0.5V hysteresis, except in shutdown,
when receivers R4 and R5 have no hysteresis.
When entering shutdown with receivers active, R4 and
R5 are not valid until 80µs after SHDNis driven low.
When coming out of shutdown, all receiver outputs are
invalid until the charge pumps reach nominal voltage
levels (less than 2ms when using 0.1µF capacitors).
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against
electrostatic discharges encountered during handling
and assembly. The driver outputs and receiver inputs
have extra protection against static electricity. Maxim’s
engineers developed state-of-the-art structures to
protect these pins against ESD of ±15kV without
damage. The ESD structures withstand high ESD in all
states: normal operation, shutdown, and powered
down. After an ESD event, Maxim’s Eversions keep
working without latchup, whereas competing RS-232
products can latch and must be powered down to
remove latchup.
ESD protection can be tested in various ways; the
transmitter outputs and receiver inputs of this product
family are characterized for protection to the following
limits:±15kV using the Human Body Model±8kV using the contact-discharge method specified
in IEC1000-4-2±15kV using IEC1000-4-2’s air-gap method.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test set-up, test methodology, and test results.
Human Body Model
Figure 6a shows the Human Body Model, and Figure
6b shows the current waveform it generates when
discharged into a low impedance. This model consists
of a 100pF capacitor charged to the ESD voltage of
interest, which is then discharged into the test device
through a 1.5kΩresistor.
MAX202E–MAX213E, MAX232E/MAX241E
±15kV ESD-Protected, +5V RS-232 Transceivers ______________________________________________________________________________________
IEC1000-4-2
The IEC1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not
specifically refer to integrated circuits. The
MAX202E/MAX203E–MAX213E, MAX232E/MAX241E
help you design equipment that meets level 4 (the
highest level) of IEC1000-4-2, without the need for
additional ESD-protection components.
The major difference between tests done using the
Human Body Model and IEC1000-4-2 is higher peak
current in IEC1000-4-2, because series resistance is
lower in the IEC1000-4-2 model. Hence, the ESD
withstand voltage measured to IEC1000-4-2 is
generally lower than that measured using the Human
Body Model. Figure 7b shows the current waveform for
the 8kV IEC1000-4-2 level-four ESD contact-discharge
test.
The air-gap test involves approaching the device with a
charged probe. The contact-discharge method
connects the probe to the device before the probe is
energized.
Machine Model
The Machine Model for ESD tests all pins using a
200pF storage capacitor and zero discharge
resistance. Its objective is to emulate the stress caused
by contact that occurs with handling and assembly
during manufacturing. Of course, all pins require this
protection during manufacturing, not just RS-232 inputs
and outputs. Therefore,after PC board assembly,the
Machine Model is less relevant to I/O ports.
