♦ Low Supply Current:  
The MAX3222/MAX3232/MAX3237/MAX3241 tra ns -  
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-

MAX3241 a re g ua ra nte e d to run a t d a ta ra te s of  
120kbps while maintaining RS-232 output levels. The  
MAX3237 is guaranteed to run at data rates of 250kbps  
in the norma l op e ra ting mod e a nd 1Mb p s in the  
MegaBaud™ operating mode, while maintaining RS-232  
output levels.

♦ Flow-Through Pinout (MAX3237)  
♦ Meets EIA/TIA-232 Specifications Down to 3.0V  
♦ Guaranteed Mouse Driveability (MAX3241)  
The MAX3222/MAX3232 ha ve 2 re c e ive rs a nd 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 c omp le te s e ria l p ort (3 d rive rs /  
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-
