19-4323; Rev 17; 1/15 MAX220–MAX249 +5V-Powered, Multichannel RS-232 Drivers/Receivers General Description The MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communica- tions interfaces, particularly applications where ±12V is not available. The MAX225, MAX233, MAX235, and MAX245/MAX246/ MAX247 use no external components and are recommended for applications where printed circuit board space is critical. The MAX220-MAX249 are offered in 26 different pack- ages with temperatures from 0 to +70°C up to -55°C to +125°C. See ordering information table at the end of the data sheet for all package and temperature options. Applications • Interface Translation • Multidrop RS-232 Networks • Portable Diagnostics Equipment Benefits and Features Saves Board Space • Integrated Charge Pump Circuitry • Eliminates the Need for a Bipolar ±12V Supply • Enables Single Supply Operation from +5V Supply • Integrated Capacitors (MAX223, MAX233, MAX235, MAX245-MAX247) Saves Power for Reduced Power Requirements • 5µW Shutdown Mode AutoShutdown and UCSP are trademarks of Maxim Integrated Products, Inc.

(Note 3) 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 TOUT in high-impedance state, VSHDN or VCC = 0V. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.
