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
Ordering Information and Selection Table appears at end
of data sheet.

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. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
