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 NetworksNext-Generation Device Features♦For Low-Voltage, Integrated ESD ApplicationsMAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: +3.0V to +5.5V, Low-Power, Up to1Mbps, True RS-232 Transceivers Using Four0.1µF External Capacitors (MAX3246E Availablein a UCSP™Package)♦For Low-Cost Applications MAX221E: ±15kV ESD-Protected, +5V, 1µA,Single RS-232 Transceiver with AutoShutdown™

2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGS—MAX220/222/232A/233A/242/243

ELECTRICAL CHARACTERISTICS—MAX220/222/232A/233A/242/243(VCC= +5V ±10%, C1–C4 = 0.1µF‚ MAX220, C1 = 0.047µF, C2–C4 = 0.33µF, TA= TMINto TMAX‚ unless otherwise noted.)

Note 1:For the MAX220, V+ and V- can have a maximum magnitude of 7V, but their absolute difference cannot exceed 13V.Note 2:Input voltage measured with TOUTin high-impedance state, SHDNor VCC= 0V.Note 3:Maximum reflow temperature for the MAX233A is +225°C.

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.
