_______________Ge n e ra l De s c rip t io n  
____________________________Fe a t u re s  
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.  
Enhanced ESD Protection:  
±15kV—Human Body Model  
±8kV—IEC1000-4-2, Contact Discharge  
±15kV—IEC1000-4-2, Air-Gap Discharge  
Latchup Free During an ESD Event  
20-Pin SSOP and SO Packages  
Guaranteed 230kbps Data Rate  
Flow-Through Pinout  
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  
Pin Compatible with SN75C185  
Complete DTE Serial Port  
is less than 300µA for I  
and I , and less than 1mA

The MAX3185 is pin and functionally compatible with  
the industry-standard 75185, so existing designs can  
ins ta ntly b e c ome EMC c omp lia nt. The MAX3185 is  
available in an SO package and in the tiny SSOP that  
further reduces board space.
