MAX3209E  
General Description  
Features  
The MAX3209E is a complete, dual DTE RS-232 serial  
port (6 transmitters, 10 receivers) for motherboards and  
desktop PCs that ensures compliance with the stringent  
ESD requirements of the European Community. The  
device minimizes board space and power consumption  
by eliminating the need for a negative power supply; it  
integrates two serial ports and a charge pump into a sin-  
gle 38-pin TSSOP package.  
Two Complete Serial Ports in a Single 38-Pin  
TSSOP Package  
Requires Only +12V Supply and Logic  
Supply (+3V to +5.5V)  
No Negative Supply Required  
One Receiver Active per Port in Standby  
for System Wake-Up  
The MAX3209E features a 50µA low-power standby  
mode for compliance with system power-management  
requirements. During standby, while the device oper-  
ates from the single +3V to +5.5V logic supply, one  
receiver on each port remains active, allowing automatic  
system wake-up when peripheral communications  
resume.  
460kbps Data Rate; LapLink Compatible  
Enhanced ESD Protection  
±15kV—Human Body Model  
±8kV—IEC 1000-4-2, Contact Discharge  
±15kV—IEC 1000-4-2, Air-Gap Discharge  
Low 50µA Standby Current  
Operates with Either +3V or +5V Logic  
Guaranteed Mouse Driveability  
Small 0.1µF Capacitors  
All transmitter outputs and receiver inputs are protected  
to 15kV using ꢀEC 1000-ꢁ-2 Air-ꢂap Discharge, 8kV  
using ꢀEC 1000-ꢁ-2 Contact Discharge, and 15kV  
using the Human Body Model, making the device ideal  
for use in harsh environments or mission-critical equip-  
ment. As a result of its robust charge-pump structure,  
the MAX3209E guarantees mouse driveability and true  
RS-232 operation at data rates up to ꢁ60kbps, ensuring  
compatibility with PC-to-PC communication software
