Maxim Confidential 
MyMaxim SubscriptionsProduct Details
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–MAX249 are offered in 26 different packages 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.
Key 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
Applications/Uses
- Interface Translation
- Multidrop RS-232 Networks
- Portable Diagnostics Equipment
