MAX220–MAX249 +5V-Powered, Multichannel RS-232 Drivers/Receivers General Description Benefits and Features
The MAX220–MAX249 family of line drivers/receivers is Saves Board Space intended for all EIA/TIA-232E and V.28/V.24 communica-

tions interfaces, particularly applications where ±12V is Integrated Charge Pump Circuitry not available. • Eliminates the Need for a Bipolar ±12V Supply The MAX225, MAX233, MAX235, and MAX245/MAX246/ • Enables Single Supply Operation from +5V Supply MAX247 use no external components and are

Integrated Capacitors (MAX223, MAX233, MAX235, recommended for applications where printed circuit board space is critical. MAX245-MAX247) The MAX220-MAX249 are offered in 26 different pack- Saves Power for Reduced Power Requirements ages with temperatures from 0 to +70°C up to -55°C to

5µW Shutdown Mode +125°C. See ordering information table at the end of the data sheet for all package and temperature options.
