________________General Description  
__Next Generation Device Features  
For Smaller Packaging:  
The MAX3222/MAX3232/MAX3237/MAX3241 trans-  
ceivers have a proprietary low-dropout transmitter out-  
put stage enabling true RS-232 performance from a  
3.0V to 5.5V supply with a dual charge pump. The  
devices require only four small 0.1µF external charge-  
pump capacitors. The MAX3222, MAX3232, and  
MAX3241 are guaranteed to run at data rates of  
120kbps while maintaining RS-232 output levels. The  
MAX3237 is guaranteed to run at data rates of 250kbps  
in the normal operating mode and 1Mbps in the  
MegaBaud™ operating mode, while maintaining RS-232  
output levels.

ESD-Protected I/O and Logic Pins  
The MAX3222/MAX3232 have 2 receivers and 2  
drivers. The MAX3222 features a 1µA shutdown mode  
that reduces power consumption and extends battery  
life in portable systems. Its receivers remain active in  
shutdown mode, allowing external devices such as  
modems to be monitored using only 1µA supply cur-  
rent. The MAX3222 and MAX3232 are pin, package,  
and functionally compatible with the industry-standard  
MAX242 and MAX232, respectively.

The MAX3241 is a complete serial port (3 drivers/  
5 receivers) designed for notebook and subnotebook  
computers. The MAX3237 (5 drivers/3 receivers) is ideal  
for fast modem applications. Both these devices feature  
a shutdown mode in which all receivers can remain  
active while using only 1µA supply current. Receivers R1  
(MAX3237/MAX3241) and R2 (MAX3241) have extra out-  
puts in addition to their standard outputs. These extra  
outputs are always active, allowing external devices  
such as a modem to be monitored without forward bias-
