±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.
