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 circuitry

for single +5V supply operation. The various combinations

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 capacitors. The MAX205E

comes in a 24-pin wide DIP package, and also eliminates

external charge-pump capacitors.
