The MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications 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-MAX2.
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
