MAX3232ECUP+

Product Summary

The MAX3232ECUP+ +3.0V-powered EIA/TIA-232 and V.28/V.24 communications interface device features 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. The MAX3232ECUP+ have two receivers and two transmitters. The MAX3232ECUP+ features a 1μA shutdown mode that reduces power consumption in battery-powered portable systems. The MAX3232ECUP+ receivers remain active in shutdown mode, allowing monitoring of external devices while consuming only 1μA of supply current. The MAX3232ECUP+ and MAX3232E are pin, package, and functionally compatible with the industry-standard MAX242 and MAX232, respectively.
