General DescriptionThe MAX220–MAX249 family of line drivers/receivers isintended for all EIA/TIA-232E and V.28/V.24 communica-tions interfaces, particularly applications where ±12V isnot available. These parts are especially useful in battery-powered sys-tems, since their low-power shutdown mode reducespower dissipation to less than 5µW. The MAX225,MAX233, MAX235, and MAX245/MAX246/MAX247 useno external components and are recommended for appli-cations where printed circuit board space is critical. ________________________ApplicationsPortable ComputersLow-Power ModemsInterface TranslationBattery-Powered RS-232 SystemsMultidrop RS-232 Networks____________________________FeaturesSuperior to Bipolar♦ Operate from Single +5V Power Supply(+5V and +12V—MAX231/MAX239)♦ Low-Power Receive Mode in Shutdown(MAX223/MAX242)♦ Meet All EIA/TIA-232E and V.28 Specifications♦ Multiple Drivers and Receivers♦ 3-State Driver and Receiver Outputs♦ Open-Line Detection (MAX243)Ordering InformationOrdering Information continued at end of data sheet.*Contact factory for dice specifications.MAX220–MAX249+5V-Powered, Multichannel RS-232Drivers/Receivers________________________________________________________________ Maxim Integrated Products 1Selection Table19-4323; Rev 9; 5/00PARTMAX220CPEMAX220CSEMAX220CWE 0°C to +70°C0°C to +70°C0°C to +70°CTEMP.
