General Description

Next-Generation Device Features

♦ For Space-Constrained Applications

MAX3228E/MAX3229E: ±±15k ESꢀ-ꢁrotectedꢂ

+2.1k to +1.1kꢂ RS-232 Transceivers in UCSꢁ

♦ For Low-koltage or ꢀata Cable Applications

2Tx/2Rxꢂ RS-232 Transceivers with ±±15k

ESꢀ-ꢁrotected I/O and Logic ꢁins

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 ±1ꢀ5V using IEꢁ 1000-4-2 Air-ꢂap

Discharge, ±85V using IEꢁ 1000-4-2 ꢁontact Discharge

(±±5V for MAX3246E), and ±1ꢀ5V using the ꢃuman ꢄodꢅ

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 ±1ꢀ5V using the ꢃuman

ꢄodꢅ Model.

Applications

ꢄatterꢅ-Powered Equipment

ꢁell Phones Smart Phones

ꢁell-Phone Data ꢁables

Noteboo5, Subnoteboo5, and Palmtop ꢁomputers

Printers

A proprietarꢅ low-dropout transmitter output stage delivers

true RS-232 performance from a +3.0V to +ꢀ.ꢀV power

supplꢅ, using an internal dual charge pump. The charge

pump requires onlꢅ four small 0.1µF capacitors for opera-

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

tion at data rates of 2ꢀ05bps while maintaining RS-232

output levels. The MAX3237E guarantees operation at

2ꢀ05bps in the normal operating mode and 1Mbps in the

Megaꢄaud™ 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 batterꢅ-pow-

ered portable sꢅstems. The MAX3222E receivers remain

active in shutdown mode, allowing monitoring of external

devices while consuming onlꢅ 1µA of supplꢅ current. The

MAX3222E and MAX3232E are pin, pac5age, and func-

tionallꢅ compatible with the industrꢅ-standard MAX242

and MAX232, respectivelꢅ.

The MAX3241E/MAX3246E are complete serial ports

(three drivers/five receivers) designed for noteboo5 and

subnoteboo5 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 onlꢅ 1µA (MAX3241E/MAX3246E) or 10nA

(MAX3237E).
