EVALUATION KIT AVAILABLE

General Description

The MAX202E-MAX213E, MAX232E, and MAX241E are a

family of RS-232 and V.28 transceivers with high ±15kV

ESD HBM protection and integrated charge pump circuit-

ry for single +5V supply operation. The various combina-

tions of features are outlined in the

Selector Guide.

The

drivers and receivers for all ten devices meet all EIA/TIA-

232E and CCITT V.28 specifications at data rates up to

120kbps when loaded.

The MAX211E/MAX213E/MAX241E are available in 28-

pin SO and SSOP packages. The MAX202E/MAX232E

come in 16-pin TSSOP, narrow SO, wide SO, and DIP

packages. The MAX203E comes in a 20-pin DIP/SO

package, and needs no external charge-pump capaci-

tors. The MAX205E comes in a 24-pin wide DIP pack-

age, and also eliminates external charge-pump

capacitors.

Detailed Description

The MAX202E–MAX213E, MAX232E/MAX241E consist of

three sections: charge-pump voltage converters, dri-

vers (transmitters), and receivers. These E versions

provide extra protection against ESD. They survive

±15kV discharges to the RS-232 inputs and outputs,

tested using the 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 fre-

quently 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 capaci-

tor, C4.

In shutdown mode, V+ is internally connected to VCC by

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 receiv-

er. 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 oper-

ating 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 uncon-

nected 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.

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 imped-

ance.

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 to respond 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 sup-

ply 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-shut-

down receivers can monitor external activity while main-

taining 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

(SHDN), but is active low for the MAX213E (SHDN).

The MAX213E’s receiver propagation delay is typically

0.5µs in normal operation. In shutdown mode, propaga-

tion 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 SHDN is 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 electro-

static discharges encountered during handling and

assembly. The driver outputs and receiver inputs have

extra protection against static electricity. Maxim’s engi-

neers 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 E versions 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:

1) ±15kV using the Human Body Model

2) ±8kV using the contact-discharge method specified

in IEC1000-4-2

3) ±15kV using IEC1000-4-2’s air-gap method.

ESD Test Conditions

ESD performance depends on a variety of conditions.

est, which is then discharged into the test device

through a 1.5kΩresistor.

IEC1000-4-2

The IEC1000-4-2 standard covers ESD testing and per-

formance 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 high-

est level) of IEC1000-4-2, without the need for addition-

al 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 with-

stand 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 con-

nects the probe to the device before the probe is ener-

gized.

Machine Model

The Machine Model for ESD tests all pins using a

200pF storage capacitor and zero discharge resis-

tance. Its objective is to emulate the stress caused by

contact that occurs with handling and assembly during

manufacturing. Of course, all pins require this protec-

tion during manufacturing, not just RS-232 inputs and

Applications Information

Capacitor Selection

The capacitor type used for C1–C4 is not critical for

proper operation. The MAX202E, MAX206–MAX208E,

MAX211E, and MAX213E require 0.1µF capacitors,

and the MAX232E and MAX241E require 1µF capaci-

tors, although in all cases capacitors up to 10µF can

be used without harm. Ceramic, aluminum-electrolytic,

or tantalum capacitors are suggested for the 1µF

capacitors, and ceramic dielectrics are suggested for

the 0.1µF capacitors. When using the minimum recom-

mended capacitor values, make sure the capacitance

value does not degrade excessively as the operating

temperature varies. If in doubt, use capacitors with a

larger (e.g., 2x) nominal value. The capacitors’ effec-

tive series resistance (ESR), which usually rises at low

temperatures, influences the amount of ripple on V+

and V-.

Use larger capacitors (up to 10µF) to reduce the output

impedance at V+ and V-. This can be useful when

“stealing” power from V+ or from V-. The MAX203E and

MAX205E have internal charge-pump capacitors.

Bypass VCC to ground with at least 0.1µF. In applica-

tions sensitive to power-supply noise generated by the

charge pumps, decouple VCC to ground with a capaci-

tor the same size as (or larger than) the charge-pump

capacitors (C1–C4).

V+ and V- as Power Supplies

A small amount of power can be drawn from V+ and V-,

although this will reduce both driver output swing and

noise margins. Increasing the value of the charge-pump

capacitors (up to 10µF) helps maintain performance

when power is drawn from V+ or V-.

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

The driver outputs display no ringing or undesirable

transients as they come out of shutdown.

High Data Rates

These transceivers maintain the RS-232 ±5.0V mini-

mum driver output voltages at data rates of over

120kbps. For data rates above 120kbps, refer to the

Transmitter Output Voltage vs. Load Capacitance

graphs in the

Typical Operating Characteristics

Communication at these high rates is easier if the

capacitive loads on the transmitters are small; i.e.,

short cables are best.
