The MAX3222E/MAX3232E/MAX3237E/MAX3241E/

MAX3246E +3.0V-powered EIA/TIA-232 and V.28/V.24

communications interface devices feature low power con-

sumption, 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 transmit-

ter 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 opera-

tion from a +3.3V supply. Each device guarantees opera-

tion 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-pow-

ered 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 func-

tionally 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/

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 1µA (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.

The MAX3246E is offered in the ultra-small 6 x 6 UCSP™

package.
