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
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
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 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. 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.
