19-1298; Rev 3a; 1/00  
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.  
10nA (MAX3237E)  
o Flow-Through Pinout (MAX3237E)  
o Guaranteed Mouse Driveability (MAX3241E)  
o Meets EIA/TIA-232 Specifications Down to 3.0V
