ADM231L-ADM234L/ADM236L-ADM241L GENERAL INFORMATION
ADM231L-ADM234L/ADM236L-ADM241L family RS-232 drivers/receivers designed solve interface problems meeting EIA-232-E specifications while using single digital supply. EIA-232-E standard requires that transmitters deliver minimum transmission channel that receivers accept signal levels down ADM231L-ADM234L/ADM236L-ADM241L meet these requirements integrating step-up voltage converters level-shifting transmitters receivers onto same chip. CMOS technology used keep power dissipation absolute minimum. comprehensive range transmitter/ receiver combinations available most communications needs. ADM236L ADM241L particularly useful battery-powered systems because they feature power shutdown mode that reduces power dissipation less than ADM233L designed applications which space saving important because charge pump capacitors molded into package. ADM231L ADM239L include only negative charge pump converter intended applications which available. facilitate sharing common line connection microprocessor data bus, ADM236L, ADM239L, ADM241L feature enable (EN, function.

internal circuitry ADM236L ADM241L consists three main sections: charge pump voltage converter, RS-232-toTTL/CMOS receivers, TTL/CMOS-to-RS-232 transmitters.
Charge Pump DC-to-DC Voltage Converter
charge pump voltage converter consists oscillator switching matrix. converter generates supply from input. This done stages using switched capacitor technique, illustrated Figure Figure First, input supply doubled using capacitor charge storage element. level then inverted generate using storage element.

With driving typical EIA-232-E load, output voltage swing Even under worst-case conditions, drivers guaranteed meet EIA-232-E minimum requirement. input threshold levels both TTL- CMOS-compatible with switching threshold VCC/4. With nominal switching threshold 1.25 typical.

APPLICATION HINTS
Driving Long Cables
accordance with EIA-232-E standard, long cables permissible, provided that total load capacitance does exceed 2500 longer cables that exceed this, possible trade baud rate cable length. Large load capacitances cause reduction slew rate; therefore, maximum transmission baud rate decreased. ADM236L ADM241L designed minimize slew rate reduction that occurs load capacitance increases. receivers, important that high level noise immunity built that slow rise fall times cause multiple output transitions signal passes slowly through transition region. ADM236L ADM241L have 0.65 hysteresis guard against this. This ensures that even noisy environments error-free reception achieved.
Shutdown (SD)
ADM236L ADM241L feature control input that used disable part reduce power consumption less than This very useful battery-operated systems. During shutdown, charge pump turned off, transmitters disabled, receivers into high impedance, disabled state. shutdown control input active high parts (see Table
High Baud Rate Operation
ADM236L ADM241L feature high slew rates, permitting data transmission rates well excess EIA-232-E specification. drivers maintain signal levels data rates kbps under worst-case loading conditions.
