Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.Electrical Characteristics

Transition Slew-Rate CircuitDetailed Description
The MAX202E–MAX213E, MAX232E/MAX241E consist ofthree sections: charge-pump voltage converters, dri-vers (transmitters), and receivers. These E versionsprovide extra protection against ESD. They survive±15kV dischargesto the RS-232 inputs andoutputs,testedusingthe Human Body Model. When testedaccording to IEC1000-4-2, they survive ±8kV contact-discharges and ±15kV air-gap discharges. The ruggedE versions are intended for use in harsh environmentsor applications where the RS-232 connection is fre-quently changed (such as notebook computers). Thestandard (non-“E”) MAX202, MAX203, MAX205–MAX208, MAX211, MAX213, MAX232, and MAX241 arerecommended for applications where cost is critical.
into -10V, storing the -10V on the V- output filter capaci-tor, C4.
In shutdown mode, V+ is internally connected to VCCbya 1kΩpull-down resistor, and V- is internally connectedto ground by a 1kΩpull up resistor.
RS-232 Drivers
With VCC= 5V, the typical driver output voltage swingis ±8V when loaded with a nominal 5kΩRS-232 receiv-er. The output swing is guaranteed to meet EIA/TIA-232E and V.28 specifications that call for ±5V minimumoutput levels under worst-case conditions. Theseinclude a 3kΩload, minimum VCC, and maximum oper-ating temperature. The open-circuit output voltageswings from (V+ - 0.6V) to V-.
Input thresholds are CMOS/TTL compatible. Theunused drivers’ inputs on the MAX205E–MAX208E,MAX211E, MAX213E, and MAX241E can be left uncon-nected because 400kΩpull up resistors to VCCareincluded on-chip. Since all drivers invert, the pull upresistors force the unused drivers’ outputs low. TheMAX202E, MAX203E, and MAX232E do not have pullup resistors on the transmitter inputs.

+5V to ±10V Dual Charge-PumpVoltage Converter
The +5V to ±10V conversion is performed by dual charge-pump voltage converters (Figure 4). The first charge-pump converter uses capacitor C1 to double the +5V into +10V, storing the +10V on the output filter capacitor, C3. The second uses C2 to invert the +10V
