General Description
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.
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.
All transmitter outputs and receiver 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, 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 460kbps, ensuring
compatibility with PC-to-PC communication software
(such as LapLink
).
