♦ 1µA Supply Current

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.

♦ AutoShutdown Plus—EDN Innovation of the Year

♦ Guaranteed Data Rate:

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

re volutiona ry AutoShutd own Plus ™ fe a ture . The s e

d e vic e s a utoma tic a lly e nte r a low-p owe r s hutd own

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-

e r inp ut. AutoShutd own Plus s a ve s p owe r without

changes to the existing BIOS or operating system.

250kbps (MAX3224/3226/3244)

1Mbps (MAX3225/3227/3245)

♦ Guaranteed Slew Rate:

6V/µs (MAX3224/3226/3244)

24V/µs (MAX3225/3227/3245)

♦ Meets EIA/TIA-232 Specifications Down to 3.0V

♦ Guaranteed Mouse Driveability (MAX3244/3245)

♦ Ready-to-Transmit Logic-Level Output

The MAX3225/MAX3227/MAX3245 a ls o fe a ture

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.
