Maxim MAX3237E Manuals

The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E are +3.0V-powered EIA/TIA-232 and V.28/V.24 communication interface devices that offer low power consumption, high data rate capabilities, and enhanced electrostatic discharge (ESD) protection.

MAX3222E/MAX3232E/MAX3237E/MAX3241E/ MAX3246E are +3.0V powered EIA/TIA-232 and V.28/V.24 communications interface devices from Maxim, featuring low power consumption, high data rate capabilities, and enhanced electrostatic-discharge (ESD) protection. The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge (±9kV for MAX3246E), and ±15kV using the Human Body Model. The logic and receiver I/O pins of the MAX3237E are protected to the above standards, while the transmitter output pins are protected to ±15kV using the Human Body Model. A proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply, using an internal dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a +3.3V supply. Each device guarantees operation at data rates of 250kbps while maintaining RS-232 output levels. The MAX3237E guarantees operation at 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232-compliant output levels. The MAX3222E/MAX3232E have two receivers and two transmitters. The MAX3222E features a 1µA shutdown mode that reduces power consumption in battery-powered portable systems.
