General Description  
Next-Generation Device 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.  
For Low-Voltage Applications  
MAX3222E/MAX3232E/MAX3237E/MAX3241E/  
MAX3246E: ±15kV ESD-Protected Down to  
10nA, +3.0V to +5.5V, Up to 1Mbps, True RS-232  
Transceivers (MAX3246E Available in a UCSP™  
Package)  
For Low-Power Applications  
MAX3221/MAX3223/MAX3243: 1µA Supply  
Current, True +3V to +5.5V RS-232 Transceivers  
with Auto-Shutdown™  
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.  
For Space-Constrained Applications  
MAX3233E/MAX3235E: ±15kV ESD-Protected,  
1µA, 250kbps, +3.0V/+5.5V, Dual RS-232  
Transceivers with Internal Capacitors  
For Low-Voltage or Data Cable Applications  
MAX3380E/MAX3381E: +2.35V to +5.5V, 1µA,  
2Tx/2Rx RS-232 Transceivers with ±15kV ESD-  
Protected I/O and Logic Pins
