_______________General Description
The MAX202E–MAX213E, MAX232E/MAX241E line
drivers/receivers are designed for RS-232 and V.28
communications in harsh environments. Each
transmitter output and receiver input is protected
against ±15kV electrostatic discharge (ESD) shocks,
without latchup. The various combinations of features
are outlined in the
Selection 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 in accordance with the EIA/TIA-232E
specification.
The MAX211E/MAX213E/MAX241E are available in 28-
pin SO packages, as well as a 28-pin SSOP that uses
60% less board space. The MAX202E/MAX232E come
in 16-pin 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. The
MAX206E/MAX207E/MAX208E come in 24-pin SO,
SSOP, and narrow DIP packages. The MAX232E/
MAX241E operate with four 1µF capacitors, while the
MAX202E/MAX206E/MAX207E/MAX208E/MAX211E/
MAX213E operate with four 0.1µF capacitors, further
reducing cost and board space.
