MAX3209E Datasheet | Maxim Integrated

Description The MAX3209E is a plete, dual DTE RS-232 serial port (6 transmitters, 10 receivers) for motherboards and desktop PCs that ensures pliance with the stringent ESD requirements of the European munity. 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 pliance 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 munications resume. All transmitter outputs and receiver inputs are protected to ±15k V using IEC 1000-4-2 Air-Gap Discharge, ±8k V using IEC 1000-4-2 Contact Discharge, and ±15k V using the Human Body Model, making the device ideal for use in harsh environments or mission-critical equipment. 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 patibility with PC-to-PC munication software (such as Lap Link™).
