The MAX3222/MAX3232/MAX3237/MAX3241 transceivers have a proprietary low-dropout transmitter output 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 chargepump 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.
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 current. The MAX3222 and MAX3232 are pin， package，
and functionally compatible with the industry-standard
MAX242 and MAX232， respectiv
