+5V-Powered, Multichannel MAX220MAX249 RS-232 Drivers/Receivers General Description Benefits and Features The MAX220MAX249 family of line drivers/receivers is Saves Board Space intended for all EIA/TIA-232E and V.28/V.24 communica- Integrated Charge Pump Circuitry tions interfaces, particularly applications where 12V is Eliminates the Need for a Bipolar 12V Supply not available. Enables Single Supply Operation from +5V Supply The MAX225, MAX233, MAX235, and MAX245/MAX246/ MAX247 use no external components and are Integrated Capacitors (MAX223, MAX233, MAX235, recommended for applications where printed circuit MAX245-MAX247) board space is critical. Saves Power for Reduced Power Requirements The MAX220-MAX249 are offered in 26 different pack- ages with temperatures from 0 to +70C up to -55C to 5W Shutdown Mode +125C. See ordering information table at the end of the data sheet for all package and temperature options. Ordering Information and Selection Table appears at end of data sheet.
