MAX3222E Overview
Description
The MAX3222E/MAX3232E/MAX3237E/MAX3241E/ MAX3246E +3.0V-powered EIA/TIA-232 and V.28/V.24 communications interface devices feature 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.
Key Features
- low power consumption, high data-rate capabilities, and enhanced electrostatic-discharge (ESD) protection
- 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 MAX3222E/MAX3232E have two receivers and two transmitters
- The MAX3222E features a 1μA shutdown mode that reduces power consumption in battery-powered portable systems
- The MAX3222E receivers remain active in shutdown mode, allowing monitoring of external devices while consuming only 1μA of supply current
- The MAX3222E and MAX3232E are pin, package, and functionally compatible with the industry-standard MAX242 and MAX232, respectively
- The MAX3241E/MAX3246E are complete serial ports (three drivers/five receivers) designed for notebook and subnotebook computers
- The MAX3237E (five drivers
