【15kV ESD-Protected, EMC-Compliant, 230kbps RS-232 Serial Port for Motherboards/Desktop PCs
_______________General Description
The MAX3185 is a complete DTE RS-232 serial port
designed to meet the stringent ESD requirements of the
European community. All transmitter outputs and receiv-
er inputs are protected to ±15kV using IEC 1000-4-2
Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact
Discharge, and ±15kV using the Human Body Model.
The MAX3185 has three RS-232 transmitters, five RS-
232 receivers, and no charge pump, optimizing it for
operation in desktop PC and motherboard applications.
It is guaranteed to run at data rates up to 230kbps, pro-
viding compatibility with popular software for communi-
cating with personal computers. Power-supply current
is less than 300µA for IDDand ISS, and less than 1mA
for ICC.
The MAX3185 is pin and functionally compatible with
the industry-standard 75185, so existing designs can
instantly become EMC compliant. The MAX3185 is
available in an SO package and in the tiny SSOP that
further reduces board space.

_______________Detailed Description
±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 MAX3185 driver outputs and receiver
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 ESD of ±15kV, without damage. After an ESD
event, the MAX3185 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:±15kV using the Human Body Model±8kV using the Contact-Discharge Method specified
in IEC1000-4-2 (formerly IEC801-2)±15kV using the Air-Gap Method specified in
IEC1000-4-2 (formerly IEC801-2)
ESD Test Conditions

ESD performance depends on a number of conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.

Figure 1a. IEC1000-4-2 ESD Test Model
Figure 1b. IEC1000-4-2 ESD-Generator Current Waveform
Human Body Model
Figure 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
1.5kΩresistor.
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 MAX3185 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. Because series resistance is
lower in the IEC1000-4-2 ESD test model (Figure 1a),
the ESD withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model. Figure 1b 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 connects
the probe to the device before the probe is energized.
Machine Model

The 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.
__________Applications Information

Use proper layout to ensure other devices on your
board are not damaged in an ESD strike. Currents as
high as 60A can instantaneously pass into ground, so
be sure to minimize the ground-lead return path to the
power supply. A separate return path to the power sup-
ply is recommend. Trace widths should be greater than
40 mils. Bypass VCC, VDD, and VSSwith 0.1µF capaci-
tors as close to the part as possible to ensure maxi-
mum ESD protection.
Tie any unused transmitter inputs to GND or VCC. No
external protection diodes are needed because the
MAX3185 is not sensitive to power-supply sequencing.
