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 single 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 operates 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 equipment. In addition, the MAX3209E withstands ±4kV per IEC 1000-4-4 Electrical Fast Transient/Burst Stressing. 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®).
