MAX3186EAP

P1-P3P4-P6P7-P8
_______________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
I
DD
and I
SS
, and less than 1mA for I
CC
.
The MAX3186 is available in an SO package and in the
tiny SSOP that further reduces board space.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
