1 General DescriptionThe MAX3222E/MAX3232E/MAX3237E/MAX3241E /MAX3 246E + EIA/TIA-232 and 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. The logic and receiver I/O pins of the MAX3237E are pro-tected to the above standards, while the transmitter output pins are protected to 15kV using the Human Body proprietary low-dropout transmitter output stage deliv-ers true RS-232 performance from a + to + power supply, using an internal dual charge pump.

2 The charge pump requires only four small F capacitors for operation from a + supply. Each device guaran-tees operation at data rates of 250kbps while maintaining RS-232 output levels. The MAX3237E guarantees opera-tion at 250kbps in the normal operating mode and 1 Mbps in the MegaBaud operating mode, while maintaining RS-232-compliant output MAX3222E/MAX3232E have two receivers and two transmitters. The MAX3222E features a 1 A shutdown mode that reduces power consumption in battery-pow-ered portable systems. The MAX3222E receivers remain active in shutdown mode, allowing monitoring of external devices while consuming only 1 A of supply current.

3 The MAX3222E and MAX3232E are pin, package, and func-tionally compatible with the industry-standard MAX242 and MAX232, MAX3241E/MAX3246E are complete serial ports (three drivers/five receivers) designed for notebook and subnotebook computers. The MAX3237E (five drivers/three receivers) is ideal for peripheral applications that require fast data transfer. These devices feature a shut-down mode in which all receivers remain active, while consuming only 1 A (MAX3241E/MAX3246E) or 10nA (MAX3237E).The MAX3222E, MAX3232E, and MAX3241E are avail-able in space-saving SO, SSOP, TQFN and TSSOP pack-ages. The MAX3237E is offered in an SSOP package.

(Notes 3, 4)Note 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 2: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device can be exposed to during board-level solder attach and rework.
