1ꢀ5k EꢁDꢂ-rotected, +ꢀk Rꢁꢂ232 Transceivers
_______________General Description
____________________________Features
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 1ꢀ5V
electrostatic discharge (ESD) shoc5s, 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 1205bps, when loaded
in accordance with the EIA/TIA-232E specification.
ꢀ ESD Protection for RS-232 I/O Pins:
15kV—Human Body Model
8kV—IEC1000-4-2, Contact Discharge
15kV—IEC1000-4-2, Air-Gap Discharge
ꢀ Latchup Free (unlike bipolar equivalents)
ꢀ Guaranteed 120kbps Data Rate—LapLink™
Compatible
ꢀ Guaranteed 3V/µs Min Slew Rate
The MAX211E/MAX213E/MAX241E are available in 28-
pin SO pac5ages, 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
pac5ages. The MAX203E comes in a 20-pin DIP/SO
pac5age, and needs no external charge-pump
capacitors. The MAX20ꢀE comes in a 24-pin wide DIP
pac5age, and also eliminates external charge-pump
capacitors. The MAX206E/MAX207E/MAX208E come in
24-pin SO, SSOP, and narrow DIP pac5ages. 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.
ꢀ Operate from a Single +5V Power Supply
