with AutoShutdown Plus

General Description

Next Generation Device Features

● For Space-Constrained Applications:

The MAX3224E/MAX3225E/MAX3226E/MAX3227E/

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

V.28/V.24 communications interfaces with automatic shut-

down/wakeup features, high data-rate capabilities, and

enhanced electrostatic discharge (ESD) protection. All

transmitter outputs and receiver inputs are protected to

±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using

IEC 1000-4-2 Contact Discharge, and ±15kV using the

Human Body Model.

MAX3228E/MAX3229E: ±15kV ESD-Protected,

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

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 1μA supply current using Maxim’s

revolutionary AutoShutdown Plus™ feature. These devic-

es automatically 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 30

seconds. They turn on again when they sense a valid

transition at any transmitter or receiver input.

AutoShutdown Plus saves power without changes to the

existing BIOS or operating system.

The MAX3225E/MAX3227E/MAX3245E also fea-

ture MegaBaud™ operation, guaranteeing 1Mbps for

high-speed applications such as communicating with

ISDN modems. The MAX3224E/MAX3226E/MAX3244E

guarantee 250kbps operation. The transceivers have a

proprietary low-dropout transmitter output stage enabling

true RS-232 performance from a +3.0V to +5.5V supply

with a dual charge pump. The charge pump requires only

four small 0.1μF capacitors for operation from a 3.3V

supply. The MAX3224E–MAX3227E feature a logic-level

output (READY) that asserts when the charge pump is

regulating and the device is ready to begin transmitting.
