±15kV ESD-Protected, EMC-Compliant, 230kbps
RS-232 Serial Port for Modems
_______________General Description
The MAX3186 is a complete DCE 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 MAX3186 has five RS-232 transmitters, three RS-
232 receivers, and no charge pump, optimizing it for
operation in modem applications. It is guaranteed to
run at data rates up to 230kbps, providing compatibility
with popular software for communicating with personal
computers. Power-supply current is less than 300µA for
IDD and ISS, and less than 1mA for ICC.
The MAX3186 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 MAX3186 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 MAX3186 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 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.
