15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V,

Up to 1Mbps, True RS-232 Transceivers

________________General Description

____________________________Features

o ESD Protection for RS-232 I/O Pins

(MAX3222E/MAX3232E/MAX3241E)

15kV—Human Body Model

The MAX3222E/MAX3232E/MAX3237E/MAX3241E are

3V-powered EIA/TIA-232 and V.28/V.24 communications

interfaces with low power requirements, high data-

rate capabilities, and enhanced electrostatic discharge

(ESD) protection. All transmitter outputs and receiver

inputs are protected to 1ꢀ5V using IEꢁ 1ꢂꢂꢂ-4-2 Air-

Gap Discharge, 85V using IEꢁ 1ꢂꢂꢂ-4-2 ꢁontact Dis-

charge, and 1ꢀ5V using the ꢃuman ꢄodꢅ Model. The

MAX3237E’s logic and receiver I/O pins are protected to

the above standards, while the transmitter output pins are

protected to 1ꢀ5V using the ꢃuman ꢄodꢅ Model.

8kV—IEC 1000-4-2, Contact Discharge

15kV—IEC 1000-4-2, Air-Gap Discharge

o ESD Protection for All Logic and Receiver I/O

Pins (MAX3237E)

15kV—Human Body Model

8kV—IEC 1000-4-2, Contact Discharge

15kV—IEC 1000-4-2, Air-Gap Discharge

o ESD Protection for Transmitter Output Pins

(MAX3237E)

15kV—Human Body Model

o Guaranteed Data Rate

250kbps (MAX3222E/MAX3232E/MAX3241E

and MAX3237E, normal operation)

1Mbps (MAX3237E, MegaBaud operation)

o Latchup Free

o Low-Power Shutdown with Receivers Active

1µA (MAX3222E/MAX3241E)

The transceivers have a proprietarꢅ low-dropout transmit-

ter output stage, delivering true RS-232 performance from

a +3.ꢂV to +ꢀ.ꢀV supplꢅ with a dual charge pump. The

charge pump requires onlꢅ four small ꢂ.1µF capacitors

for operation from a +3.3V supplꢅ. Each device is guaran-

teed to run at data rates of 2ꢀꢂ5bps while maintaining RS-

232 output levels. The MAX3237E is guaranteed to run at

data rates of 2ꢀꢂ5bps in the normal operating mode and

1Mbps in the Megaꢄaud™ operating mode while main-

taining RS-232-compliant output levels.

The MAX3222E/MAX3232E have two receivers and two

drivers. The MAX3222E features a 1µA shutdown mode

that reduces power consumption and extends batterꢅ

life in portable sꢅstems. Its receivers can remain active

in shutdown mode, allowing external devices such as

modems to be monitored using onlꢅ 1µA supplꢅ current.

ꢄoth the MAX3222E and MAX3232E are pin, pac5age,

and functionallꢅ compatible with the industrꢅ-standard

MAX242 and MAX232, respectivelꢅ.

The MAX3241E is a complete serial port (three drivers/five

receivers) designed for noteboo5 and subnoteboo5 com-

puters. The MAX3237E (five drivers/three receivers) is ideal

for peripheral applications that require fast data transfer.

ꢄoth devices feature a shutdown mode in which all

receivers can remain active while using a supplꢅ cur-

rent of onlꢅ 1µA (MAX3241E) or 1ꢂnA (MAX3237E). The

MAX3237E/MAX3241E have additional receiver outputs

that alwaꢅs remain active.

The MAX3222E and MAX3232E are available in space-

saving SO, SSOP, and TSSOP pac5ages. The MAX3241E

is available in SO and SSOP pac5ages. The MAX3237E is

available in an SSOP pac5age.
