15kV ESD-Protected / EMC-Compliant / 230kbps / 3-Tx/3-Rx RS-232 IC
_______________General DescriptionThe MAX1406 is an RS-232 IC designed to meet the
stringent electrostatic discharge (ESD) requirements of
the European community. All transmitter outputs and
receiver inputs are protected to ±15kV using IEC1000-4-2
Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact
Discharge, and ±15kV using the Human Body Model.
The MAX1406 has three RS-232 transmitters and three
RS-232 receivers, and is optimized for operation in
printer, modem, and telecom applications. It is guaran-
teed to run at data rates up to 230kbps, providing com-
patibility with popular software for communicating with
personal computers. Power-supply current is less than
500µA for IDDand ISS,and less than 1mA for ICC.
The MAX1406 is pin and functionally compatible with the
industry-standard MC145406, so existing designs can
instantly become Electromagnetic Compatibility (EMC)
compliant. The MAX1406 is available in DIP and SO pack-
ages, and in a tiny SSOP that reduces board space.

_______________Detailed Description
RS-232 TransmittersThe transmitters are inverting level translators that con-
vert CMOS-logic input levels to an EIA/TIA-232 voltage
between ±5V and ±13.2V, into a load between 3kWand
7kW. The MAX1406 guarantees a 230kbps data rate
with a worst-case load of 3kW and 1000pF, providing
compatibility with PC-to-PC communication software.
When the power is off, the MAX1406 outputs are permit-
ted to be driven up to ±15V. The transmitter inputs do
not have internal pull-up resistors. Connect unused
inputs to GND or VCC.
RS-232 ReceiversThe receiver inputs invert and convert the RS-232 sig-
nals to CMOS-logic output levels. The MAX1406 has
hysteresis of 650mV. The receiver output swings
between GND and VCC.
±15kV ESD ProtectionAs with all Maxim devices, electrostatic discharge
(ESD) protection structures are incorporated on all pins
to protect against ESD encountered during handling
and assembly. The MAX1406 driver outputs and receiv-
er inputs have extra protection against static electricity
found in normal operation. Maxim’s engineers devel-
oped state-of-the-art structures to protect these pins
against ±15kV ESD without damage. After an ESD
event, the MAX1406 continues working without latchup.
ESD protection can be tested in several ways. The
transmitter outputs and the receiver inputs are charac-
terized for protection to the following:
1) ±15kV using the Human Body Model
2) ±8kV using the Contact-Discharge method specified
in IEC1000-4-2 (formerly IEC801-2)
3) ±15kV using the Air-Gap Discharge method speci-
fied in IEC1000-4-2 (formerly IEC801-2)
ESD Test ConditionsESD performance depends on a number of conditions.

test setup, methodology, and results.

______________________________________________________________Pin Description
MAX1406
Human Body ModelFigure 2a shows the Human Body Model, and Figure
2b shows the current waveform it generates when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter-
est, which is then discharged into the device through a
1.5kWresistor.
IEC1000-4-2The IEC1000-4-2 standard covers ESD testing and per-
formance of finished equipment; it does not specifically
refer to integrated circuits. The MAX1406 helps you
design equipment that meets Level 4 (the highest level)
of IEC1000-4-2, without additional ESD-protection com-
ponents.
The main difference between tests done using the
Human Body Model and IEC1000-4-2 is higher peak
current in IEC1000-4-2 (Figure 3). Because series resis-
tance is lower in the IEC1000-4-2 ESD test model, the
ESD withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model. Figure 3b shows the current waveform for
the ±8kV IEC1000-4-2 Level 4 ESD Contact-Discharge
test.
The Air-Gap test involves approaching the device with
a charge probe. The Contact-Discharge method con-
nects the probe to the device before the probe is ener-
gized.
Machine ModelThe Machine Model for ESD testing uses a 200pF stor-
age capacitor and zero-discharge resistance. It mimics
the stress caused by handling during manufacturing
and assembly. Of course, all pins (not just RS-232
inputs and outputs) require this protection during man-
ufacturing. Therefore, the Machine Model is less rele-
vant to the I/O ports than are the Human Body Model
and IEC1000-4-2.
