±15kV ESD-Protected, +5V RS-232 Transceivers
_______________General Description
T h e MAX202EMAX213E, MAX232E/MAX241E line dri v e r s / r e c e i v e r s 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 d e v i c e s 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 28pin SO packages, as well as a 28-pin SSOP that uses 60% less board space. The MAX202E/MAX232E come i n 16-pin TSSOP, narrow SO, wide SO, and DIP packages. The MAX203E comes in a 20-pin DIP/SO p a c k a g e , 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 2 4 - p i n SO, SSOP, and narrow DIP packages. The MAX232E/MAX241E operate with four 1µF capacitors, w h i l e the MAX202E/MAX206E/MAX207E/MAX208E/ MAX211E/MAX213E operate with four 0.1µF capacitors, further reducing cost and board space.

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.
