MAX3224–MAX3227/

MAX3244/MAX3245

1µA Supply Current, 1Mbps, 3.0V to 5.5V,

RS-232 Transceivers with AutoShutdown Plus

________________General Description

_Next Generation Device Features

The MAX3224–MAX3227/MAX3244/MAX3245 are 3V-

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

interfaces with automatic shutdown/wakeup features

and high data-rate capabilities.

♦ For Smaller Packaging:

MAX3228/MAX3229: +2.5V to +5.5V RS-232

Transceivers in UCSP™

♦ For Low-Voltage or Data Cable Applications:

All devices achieve a 1µA supply current using Maxim’s

revolutionary AutoShutdown Plus™ feature. These

devices 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 receiv-

er input. AutoShutdown Plus saves power without

changes to the existing BIOS or operating system.

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

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

Protected I/O and Logic Pins

♦ For Integrated ESD Protection:

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 UCSP)

The MAX3225/MAX3227/MAX3245 also feature

MegaBaud™ operation, guaranteeing 1Mbps for high-

speed applications such as communicating with ISDN

modems. The MAX3224/MAX3226/MAX3244 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 MAX3224–MAX3227 feature a logic-level output

(READY) that asserts when the charge pump is regulat-

ing and the device is ready to begin transmitting.
