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
