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 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.
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.
