EVALUATION KIT AVAILABLE
MAX202E–MAX213E,
MAX232E/MAX241E
±15kV ESD-Protected,
5V RS-232 Transceivers
General Description
The MAX202E-MAX213E, MAX232E, and MAX241E are a
family of RS-232 and V.28 transceivers with high ±15kV
ESD HBM protection and integrated charge pump circuit-
ry for single +5V supply operation. The various combina-
tions of features are outlined in the
Selector Guide.
The
drivers and receivers for all ten devices meet all EIA/TIA-
232E and CCITT V.28 specifications at data rates up to
120kbps when loaded.
The MAX211E/MAX213E/MAX241E are available in 28-
pin SO and SSOP packages. The MAX202E/MAX232E
come in 16-pin TSSOP, narrow SO, wide SO, and DIP
packages. The MAX203E comes in a 20-pin DIP/SO
package, and needs no external charge-pump capaci-
tors. The MAX205E comes in a 24-pin wide DIP pack-
age, and also eliminates external charge-pump
capacitors.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
