♦ 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-

p ump c a p a c itors . The MAX3222, MAX3232, a nd

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.

300µA (MAX3222/MAX3232/MAX3241)

500µA (MAX3237)

♦ Guaranteed Data Rate:

120kbps (MAX3222/MAX3232/MAX3241)

250kbps (MAX3237—Normal Operation)

1Mbps (MAX3237—MegaBaud Operation)

♦ 1µA Low-Power Shutdown with Receivers Active

(MAX3222/MAX3237/MAX3241)

♦ 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.

♦ Guaranteed Slew Rate:

6V/µs (MAX3222/MAX3232/MAX3237/MAX3241)

24V/µs (MAX3237—MegaBaud Operation)

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-
