±±15k ꢀEDꢁ-rotected, ±µA, 3.0k to 1.1k, 2105bps,

REꢁ232 Transceivers with AutoEhutdown

General Description

Next Generation Device Features

The MAX3221E/MAX3223E/MAX3243E are 3V-powered

EIA/TIA-232 and V.28/V.24 communications interfaces

with automatic shutdown/wakeup features, high data-

rate capabilities, and enhanced electrostatic discharge

(ESD) protection. All transmitter outputs and receiver

inputs are protected to 1ꢀkV using IEꢁ 1ꢂꢂꢂ-4-2 Air-

Gap Discharge, to 8kV using IEꢁ 1ꢂꢂꢂ-4-2 ꢁontact

Discharge, and to 1ꢀkV using the ꢃuman ꢄodꢅ Model.

o For Space-Constrained Applications:

MAX3228E/MAX3229E: 15kV ESD-Protected, +2.5V

to +5.5V RS-232 Transceivers in UCSP™

MAX3222E/MAX3232E/MAX3237E/MAX3241E/

MAX3246E: 15kV ESD-Protected Down to 10nA,

+3.0V to +5.5V, Up to 1Mbps, True RS-232

Transceivers (MAX3246E Available in a UCSP

Package)

The MAX3221E/MAX3223E/MAX3243E achieve a

1µA supplꢅ current with Maxim’s revolutionarꢅ

AutoShutdown™ feature. Theꢅ save power without

changes to the existing ꢄIOS or operating sꢅstem bꢅ enter-

ing low-power shutdown mode when the RS-232 cable is

disconnected, or when the transmitters of the connected

peripherals are off.

o For Data Cable Applications:

MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA,

2Tx/2Rx RS-232 Transceivers with 15kV ESD-

Protected I/O and Logic Pins

Ordering Information

The transceivers have a proprietarꢅ low-dropout trans-

mitter output stage, delivering true RS-232 performance

from a +3.ꢂV to +ꢀ.ꢀV supplꢅ with a dual charge pump.

The charge pump requires onlꢅ four small ꢂ.1µF capaci-

tors for operation from a +3.3V supplꢅ. Each device is

guaranteed to run at data rates of 2ꢀꢂkbps while main-

taining RS-232 output levels.

The MAX3221E contains just one driver and one receiver,

making it the smallest single-supplꢅ RS-232 transceiver.

The MAX3223E has two drivers and two receivers. The

MAX3243E is a complete 3-driver/ꢀ-receiver serial port

ideal for notebook or subnotebook computers. It also

includes two noninverting receiver outputs that are alwaꢅs

active, allowing external devices to be monitored without

forward biasing the protection diodes in circuitrꢅ that maꢅ

be powered down.
