Rꢁꢂ232 Transceivers with Autoꢁhutdown -lus

________________General Description

__Next Generation Device Features

♦ For Space-Constrained Applications:

MAX3228E/MAX3229E: 15kV ESD-Protected,

+2.5V to +5.5V, RS-232 Transceivers in UCSP

The MAX3224E/MAX3225E/MAX3226E/MAX3227E/

MAX3244E/MAX3245E are 3V-powered EIA/TIA-232

and V.28/V.24 communications interfaces with automat-

ic shutdown/wakeup features, high data-rate capabili-

ties, and enhanced electrostatic discharge (ESD)

protection. All transmitter outputs and receiver inputs

are protected to ±±5kV using IEꢀ ±111-4-2 Air-ꢁap

Discharge, ±8kV using IEꢀ ±111-4-2 ꢀontact Discharge,

and ±±5kV using the ꢂuman ꢃodꢄ Model.

MAX3222E/MAX3232E/MAX3241E^†/MAX3246E:

15kV ESD-Protected, Down to 10nA, +3.0V to

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

(MAX3246E Available in UCSP™)

♦ For Low-Voltage or 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

All devices achieve a ±µA supplꢄ current using Maxim’s

revolutionarꢄ AutoShutdown Plus™ feature. These

devices automaticallꢄ enter a low-power shutdown

mode when the RS-232 cable is disconnected or the

transmitters of the connected peripherals are inactive,

and the UART driving the transmitter inputs is inactive

for more than 31 seconds. Theꢄ turn on again when

theꢄ sense a valid transition at anꢄ transmitter or receiv-

er input. AutoShutdown Plus saves power without

changes to the existing ꢃIOS or operating sꢄstem.

The MAX3225E/MAX3227E/MAX3245E also feature

Megaꢃaud™ operation, guaranteeing ±Mbps for high-

speed applications such as communicating with ISDN

modems. The MAX3224E/MAX3226E/MAX3244E guar-

antee 251kbps operation. The transceivers have a pro-

prietarꢄ low-dropout transmitter output stage enabling

true RS-232 performance from a +3.1V to +5.5V supplꢄ

with a dual charge pump. The charge pump requires

onlꢄ four small 1.±µF capacitors for operation from a

3.3V supplꢄ. The MAX3224E–MAX3227E feature a logic-

level output (READY) that asserts when the charge

pump is regulating and the device is readꢄ to begin

transmitting.
