±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 I
DD
and I
SS
, and less than 1mA
for I
CC
.
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.
