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
