General Description The MAX3222E MAX3232E MAX3237E MAX3241E are 3V powered EIA TIA and V V communications interfaces with low power requirements high data rate capabilities and enhanced electrostatic discharge ESD protection All transmitter outputs and receiver inputs are protected to ±15kV using IEC Air Gap Discharge ±8kV using IEC Contact Dis charge and ±15kV using the Human Body Model The MAX3237E's logic and receiver I O pins are protected to the above standards while the transmitter output pins are protected to ±15kV using the Human Body Model The transceivers have a proprietary low dropout transmit ter output stage delivering true RS performance from a 0V to 5V supply with a dual charge pump The charge pump requires only four small F capacitors for operation from a 3V supply Each device is guaran teed to run at data rates of 250kbps while maintaining RS output levels The MAX3237E is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode while main taining RS compliant output levels The MAX3222E MAX3232E have two receivers and two drivers The MAX3222E features a A shutdown mode that reduces power consumption and extends battery life in portable systems Its receivers can remain active in shutdown mode allowing external devices such as modems to be monitored using only A supply current Both the MAX3222E and MAX3232E are pin package and functionally compatible with the industry standard MAX242 and MAX232 respectively The MAX3241E is a complete serial port three drivers five receivers designed for notebook and subnotebook com puters The MAX3237E five drivers three receivers is ideal for peripheral applications that require fast data transfer Both devices feature a shutdown mode in which all receivers can remain active while using a supply cur rent of only A MAX3241E or 10nA MAX3237E The MAX3237E MAX3241E have additional receiver outputs that always remain active The MAX3222E and MAX3232E are available in space saving SO SSOP and TSSOP packages The ...
