The MAX3233E/MAX3235E are EIA/TIA-232 and V.28/V.24

communications interfaces with automatic shutdown/

wa ke -up fe a ture s , hig h d a ta -ra te c a p a b ilitie s , a nd

enhanced electrostatic discharge (ESD) protection. All

transmitter outputs and receiver inputs are protected to

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

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

using the Human Body Model. The MAX3233E operates

from a +3.3V supply; the MAX3235E operates from +5.0V.

/MAX235E

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 following two conditions occur: either

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.

+3.0V to +3.6V (MAX3233E)

+4.5V to +5.5V (MAX3235E)

♦ 250kbps Guaranteed Data Rate

♦ 6V/µs Guaranteed Slew Rate

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

The MAX3233E/MAX3235E have internal dual charge

pumps requiring no external capacitors. Both trans-

ceivers have a proprietary low-dropout transmitter out-

put stage that enables true RS-232 performance from a

+3.0V to +3.6V supply for the MAX3233E or a +4.5V to

+5.5V supply for the MAX3235E. These devices are

guaranteed to operate up to 250kbps. Both are avail-

able in space-saving 20-pin wide SO or plastic DIP

packages.
